I am new here, and wanted some advice on just taking better pics in general. usually cars are my subject, weather it be my personal vehicles or other's at car shows. my camera-Nikon L18 P&S. just a simple little camera, nothin special. however, i plan on taking some pics and learning to use my brothers Nikon D80 somewhat. my latest work. just tell me what i am doing right/wrong. looking to take better pics of everything.
