You have very good instincts! A lot of your compositions are very pleasing. It is good to experiment with different f stops and shutter speeds to get a feel for what you are going for. A lot of your macros are very nice; your comic convention was also nice! I also liked the color and your capturing the movement of the dancers from the Pacific Islander gallery. Two sites that gave me decent pointers are ephotozine.com and dpreview.com. Their threads are very helpful! Keep up the good work!
