you'll want more pictures overall, you should start people in collections and break the categories up a bit more.
if you shoot it in a museum, don't make it look like a museum. clone out the string. the description should be about the store, not the method. HDR should only be used when needed, not as a filter, otherwise it looks a bit burnt. tone mapping only enhances the noise in the background. and makes it blurry looking, this could use some sharpening. i'd clone out the fan as well.
not much is in focus in this. the eye should be sharp, but everything is in motion. the background is rather noisy. the description looks like it was lifted from the site. make it less commercial, talk about the bird in your own words. not where you shot it because it could have been anywhere.
those rocks makes it look like a zoo shot. its really not in focus either. its also very small and looks silly on larger things like a duvet. i would remove the duvet or see if you can stretch it on there a bit.
this is the one you throw away. because the guys in the back tell a story, the guy that walked in front, not so much, and he's blocking most of the shot. try not to cut people in half on the right either.
leave off the frames, they only mess up products or anyone that wants a colored mat. your describing these like your in a small photo club, describe it like your talking about the place - as if its interesting. not that you stopped there for a rest. i would clone out the sign posts (in the water too). and call it an abandoned chicken coop because that's what it looks like, and it then has a target audience.
this is a better shot "stopping wise" the position is a bit odd, and its small in the frame. there is a lot of water in there. it doesn't thumbnail well other than a - what is that thing - response when your about to click.
your subjects really jump around a lot. they look like travel shots, but random. in other words, you saw stuff, you shot it, but had no direction on who it would be sold too.
the balloon is nice, but not the tree, i call it a peeping tom angle.
the rest of the stuff looks ok in general, i would work on the descriptions and try to decide who your aiming for when you shoot these.
