First of all, to understand why my art isn't that good, you have to understand that I've had absolutely no formal training (unless you count elementry school art classes). Everything I know I learned from experience or reading books, and since I've only been drawing as a hobby for about a year, that doesn't amount to much. I'm here to try to learn some new things, so if you know something that it seems I do not know, then please share.
These are some sketches I've done while trying to learn to draw reptilian forms. I've focused mainly on the head thus far, since it always seems to take me the longest to learn to draw.
Give me your comments and crits please.
