Come on guys. I just want an opinion on your thoughts about the images.

Come on guys. I just want an opinion on your thoughts about the images.

Just my two cents - actually you don't have exactly found a niche. There are uncountable pictures of flowers, many of them are good. Look at the pictures in the agencies and judge for yourself.

No, they're not! Sorry
Remember before you submit ask yourself who and why would buy my images.
SS search result for flowers 3,587,259 files....

Avoid flowers, landscapes,animals.... unless they're original and unique.
 

Not for any sale... sorry...! continue learning...

If you approve, surely never sale this images...

Thanks guys! I really appreciate the comments. Any recommendations that can help me improve?

Finally,

Ask yourself why do you want to get into this well established business? If you plan on full time than you better like working 18 hour days, taking a shower once or twice a week, and making less than $50 per day! Hate to burst your bubble but it's just a reality of the times...

Well said! I'm diamond (8351 files) but lately can't make more than 30$ per day on iS!

Because your slacking- only working 16 hour days and taking Sunday's off! Get back to to working 7 days a week and your income will reach that $50 per day level 

it's kind of hard to pass through reviewer with those photos these days.

If you look on getting accepted and selling the odd photo as a learning experience its a good hard technical training. It won't teach you much about the artistic side of photography though!

You say you have actually applied with these images? Interesting to hear what the results are if you have. I think the initial acceptance may have been made easier there as well as general submissions.
Whether they get you in or not though, I doubt if these images will make you any money on iStock or anywhere else IMHO. I wouldn't upload anything of this standard anywhere if I were you. If you do you'll end up like many other new contributors uploading hundreds of photographs and wondering why they aren't generating sales for you.
You will need to know what subjects to upload, and then you need to manage the quality of your own collection (at iStock at least), and you will need to learn the skills to do so. It's not just about getting the maximum number of images accepted. It's the quality of those images as well.
Finally, if you were a photographer who already had the skills to make commercial images, then you might make some money at stock if you were just starting. If you have to learn from the start then I think you have a long hard road ahead. There is no easy money in this game and there never was.
Good luck with whatever you decide to do.

And for managing  your iS recommendations, I recommend reading this thread, and perhaps looking through the ports of those experienced contributors reporting decreases in sales http://www.istockphoto.com/forum_messages.php?threadid=362250&page=1

hello, i won't go into the photos, as u already have the honest verdict by now.
shadysue, goofy, ... more or less told u like it is, and pointed u in the right direction.
instead of pretending all is fair n flowery (no pun intended)...

i don't know how many times one of the big guys here (SJLocke) repeated like a scratched vinyl..
" xx xx x xx xx  .. you pick the easiest type of pictures to shoot, ..the ones that are flooded in all sites", or words to that effect. which is the most frank reality-check everyone should say to all new person wanting 2 get in on this S&M business of ms

to do well , u must be able 2 provide sellable images... not images that every (to quote perry ) gwc can make. nothing wrong with sending flowers or birds or what is flooded in the ms, which is more or less every thing lncluding the kitchen sink, ... so long as what u have is unique or difficult to get.
of course, u have 2 be able 2 know ur camera so that what u shoot requires no post-processing
other than to color correct, remove fringe, locally reduce noise or sensor dust in large area where such pita are prone, ...  but not to correct bad photography, focusing, etc.
iow, the less post-processing the better, as ur images will be sparkling and clean and sharp.
therefore, when viewed on a page with other similars, it will stand out and u get chosen for downloads.

as for what u show us here, ... a soft rejection NO . this is not what u want .
the best thing 2 do is to go to each site on the right of this page here ------->>>
and look at the BEST SELLERS .
then go out and make those kinds of images.

it won't guarantee u will get sales, as many of these are aleady been on page one forever.
and ur new work will be found on pg.... (not page 1 )

but if u work with lesser known agencies, maybe there, u will be able 2 practise until u r ready
for ss, is, ...

then u better get ur anti-depressant , @nal-alcohol  or whatever u need
n get ready 4 hoop-jumping 
 

or u can just be happy with ur day job, even if it is as boring as flipping burgers (it pay more 4 sure)
or squeegee windows at the lights

then just enjoy what u like 2 shoot... dogs, cats, flowers, pretty girls,
n just give the finger 2 all the hoop jumping
