#1 Personally, I would try to get the street to go more diagonally across the picture. The street itself has some angle, but the curb is more straight up the middle. And the curb draws my eye first. If you want to be different, get down lower. Have the horizon way towards the top.
#2-5 and other landscape shots. They're too normal. For me, the trees framing on the sides of the shot are just too overdone. Unless there was something interesting in the shot. On the ocean shot and the field, there's not anchor in the foregroung. For the lone tree, its does have some interest. In the tree and its braches are very crisp. But it needs something in the sky.
#6 I would have liked to see a little bit more depth of field on the drink itself. The drink appears to be foamy, wouldn't it be great to see that foam? You can get that depth of field by seting up your dof and centering on the cup, then locking focus or recomposing or cropping in post. Also, a lensbaby would really do wonders on that shot. Perhaps some more very out of focus objects in the background? And really take advatage of all the lines you have available to use in that shot. The table edges, the straw, sides of the cup.
#7-8 I actually like these shots. Especially the dog. Its at a wierd angle. It first makes you wonder if the image was rotated the wrong way. Makes me think about the image. Only thing is maybe crop more of the right side off to get rid of the bush? But I am a sucker for images where the nose and face are in focus and the rest of the body of the animal is out of focus. I am really into shallow dof.
#9 To me, this image is very compelling. She's not just sitting there smiling. She has an inquisitive expression on her face and I love the out of focus background.
#10 Gotta be careful taking pictures of woman's butts! LOL I think this would be another lensbaby picture. Get the dog's face through the chair in focus and get everything else out of focus.
#11 I love this picture. Its not sharp, its black and white. It has an older look to it. The horizon not being level works for me too. If you straighten this horizon, everything else goes out of wack.
#12 I like the bridge, the colors, the focus. Its jus the composition. Get higher or lower if possible and crop out the dead space on the right?
Your flower shots. To me, the really white/pink roses are too blown out. Now, I think that could work, if there were softer. It looks like the second rose has a shallow dof. I would take that out of focus and if a flash was used, bouce it off a reflect of diffuse it.
I love drops of water on a plant or flower. For some real fun, get as close as you can to either see a reflection in the water drop, or see through the water drops.
If you are going to draw back and have the flower with lots of green space around it, I prefer to have that green space as out of focus as possible. Almost to were you can't see the edges between different shades of green. You want it to meld together. If you're going to have a flower off center, I like to see the stem. This will add direction and will lead the viewer's eye to the flower.
The black and white close up is really cool. Try having the center of the flower directly centered in the picture. I know this goes against conventional thinking and the rules of composition. But, look at the semetry of that flower.
The ocean shot with the rocks. To me, they need to be a bit more in focus and more to the lower left or right.
The luggage. Crop to get rid of the openess on the right. I'd like to see the edge just right of the top luggage piece. By doing this, the subject goes from lower left to upper right of the photograph.
I could be way off on these. So, just my opinions on them.
