Most of these aren't very "stock" oriented. The photo with the bottle and the couple could be a good concept photo but it is too dark and looks too out of focus. Bad lighting on the eagle, can't really tell if that's a wren on the windowsill, already LOTS of photos of mallards online. I like the christmas tree in the snow.

My personal opinion is that these types of photos might do better and be more appreciated by a site like Photocase.
http://www.photocase.com

I hadn't heard of that site so hopped over there and did one of my usual searches.
First impression: over 50% of returns on the first keyword I tried don't match the keyword. At all. Not even at a stretch.
                         Around 70% of my second keyword didn't match, but several of these, generously, could be considered a 'stretch'.
Second impression: They don't half soup up their images!
Anyone using this site? Anyone getting decent sales?

You gotta think stock...look at those pictures and think of who...customer wise... could use them? Most of them are dull and flat and lack color. Stock agencies like vibrant images, people photos in various situations, and isolated images. Believe me I know...I get rejects for that all the time. Just think before you shoot about the concept that you want to convey with that photo. You gotta look in magazines...your local grocery store ad...any advertising. That is what microstock is all about. And if you go through with this...better get use to those rejects cause it happens all the time...

You're welcome. I'm sure you will do great with audio.  

Yeah you're right there  but in the really good Vetta stuff the lighting is usually to notch. There are some Vetta pics though that just make me wonder how they got there 

At this stage I would focus more on getting your technical skills improved. Then when you are confident at the camera, try to do some stock. Most of the previous posts have correctly stated the obvious: why would someone buy this, and what could they use it for.

Haven't really read all the answers here but I think your ideas are not a lost cause - at least some of them.

First off, lose the animal pics - market is over saturated and you need to deliver outstanding execution and concept to get those accepted and sold. Just because they get accepted doesn't mean they will sell... Think about that.

In Microstock it's about volume. If you deliver great quality you'll be rewarded with lots of downloads.

IMO the last three shots are really good concepts. It's the way you executed them that killed the saleability.

Now, the couple shot on the beach. Again I really think this is a good concept with the bottle in the foreground but for a shot like this it requires a lot more preparation than aligning the bottle in the foreground with the couple in the background. With outdoor shots like this one you better be checking the light first before trying to get the shot. This may sound funny but depending on if the beach is facing North, East, South or West you have to adapt to the sunlight and see if you can frame the shot ideally. This requires some understanding in terms of composition but also directing the couples postures and the correct placement of the bottle. These are all little details that can make a huge difference if the image sells well or not so well.

The X-mas tree. Maybe this tree in particular doesn't look too flattering but I love the concept. First off how often do you see a fully decorated X-mas tree outdoors in the snow? I think it's a unique approach and that concept hasn't been covered as much as "close-up of X-mas tree with ornament" 
I'd stick to the concept and maybe try it again next year with the tree being in a better shape and hoping for a lot of snow with nice blue sky. I think by now you understand that outdoor shots really depend a lot on factors that you can't control (some you can but not all).

Search results at iStockphoto for:
"Christmas tree outdoors" = 2300 images
"Christmas tree" = 15000

And the results for the outdoor trees barely include your approach. There are very nice ones already in their collection but it's still a great idea to shoot this rather than "beautiful woman with headset" 

The bubble gum situation.

Love it! Hold a second - I love the concept. Again, the execution needs work. I think the shot is too tight/close. IMO I see Vetta shots with "not-stock worthy" concepts but obviously somebody thinks otherwise. If this would be executed nicely I could see that as a Vetta shot. It'll definitely require some post processing to get there but again, I love the concept. Something we don't see a lot.

I think you have some nifty ideas. Once you get your camera under control there might be hope 

Keep going! You'll get there.

Alex, it's the lighting. They all look dull, nothing pops out. You can't cure that in photoshop, you need to get it right when you take the shot. Backlit objects/people will look muddy unless you add fill flash or adjust the exposure to get a pure silhouette.

Photoshop can make a good shot look great. It can't make a bad shot look anything better than barely average.

Stock needs to have a message or to be useful as an element in a design. I don't think these work that way.

Hi Alex,

I guess I should have mentioned that I am a photo editor at Photocase and when I said "I would have accepted those photos" I meant as a photo-editor I would literally accept them if you uploaded them at our site (providing they are good quality at full size).
