Photography project

I've been working on my photography project these past few weeks, and the results are on Flickr ("Opposites" set). I've always wanted to learn how to take advantage of my camera's features and not just use the "auto" setting, so this project gave me a chance to do just that. Now I need feedback on the pictures so I can improve composition, etc, so if you have a spare moment please click over and have a look! Thanks ^_^;

The "Sculpture" set is the second part of my project, we had to pick a work of art and document it with pictures. The other set, "Sketches", are what I draw when I seem to be paying attention in class - judging by the cropped-off notes, I doodle the most in Roman history. >_>;;
