I liked all of these except for the second one. The randomness in the corner draws away from the center in the photo. But other than that it was descent. I'd focus on working with the lighting. The first one would have been really cool, but I can't quite put my finger on what turned me away from it... hm. But good luck, they're really nice =]
So. I'll start right off saying I've never really reviewed Art & Photography, so if I say something really stupid, ignore it, svp xD
So these were pretty interesting. The third and the sixth were my favourites-- just the colouring seems to otherworldly, the shades to sweet, calm. I really like the sunset in the sixth, just plain gorgeous.
However, the reviewer before is right. In the second picture, the thing off to the side is rather distracting and without it, the picture would be really nice. Kind of Sand of Time-ish, y'know? xD Also, in the fourth picture, I spot some spots :O They're faint, but I picked them out and I have bad eyes even with glasses. It's unfortunate, because the photo could be a really nice one.
