I wouldn't expect too much.  You've got a mishmash of walkaround shots of things that just aren't in high demand.  The kind of stuff a new contributor will upload.

Look at the SS database for similar subjects and see how yours look compared to them.

Are average "search in hard disck images to start"

Thanks for the replies. Sold two today, so I guess there's a hand for every glove!

It never hurts to get constructive criticism, but be aware that you can never predict what people will buy or what will sell well. Concentrate on improving your skills, look at what sells well and emulate the style, depth of field, etc. (for instance, typically food shots are done with a narrow DOF), and upload as much as you can. Congrats on the two sales! For having only about 20 images, that is darn good. I had 500+ in my portfolio before I started getting consistent sales, and that was back in the heyday.

All good! I do appreciate the comments. I treat every sale as a fun experience, not a make or break. Just happy and quite flattered that my work has found a home!

Just wanted to see what others thought. I have sold three photos on SS so far, but just wanted to get some idea if these photos will ever sell. Thanks in advance!

Almost the whole of these photographs are unprofessional-looking. There are lots of improvements you can learn simply reading and practicing every kind of photographic or photo-retouching forun on the internet (fstoppers and so on).
Light is poor, sad. Point of view is ordinary: like every other tourist would have shot these images. People are not models but not so interesting. There are a couple of interesting images: clean, not messy, concept-alike (feet on the water etc) .
Need LOTS of improvement with editing.
The "holidays" shots would be good with heavy enhancement in light: there is basic light good given to you by the nature, but you have to let it pop-out.

Another chance is to let LIFE pop out from your images: emotions.

You can simply browse some flyers or brochures everywhere in the world: learn the basics of the "feeling". Holidays/tourism shootings would have to go to the "next level" to sell more.

Commercial needs: 1) tecnical perfection 2) EMOTIONS 3) clear concept (very focused on "what does this say?").

So: good start but learn, improve, photoshop! And stop HDRing so much!
