I haven't had as much drawing my own designs since I was 12. That sounds strange, coming from a wannabe concept artist; but drawing from imagination has always been a process of frustration for me because I could never quite get anything on paper that looked anywhere near what I want to do.
These are terrible drawings when I look at them. Perspective is off all overthe place; line quality bad, the paper isn't even cleaned up. But I can't hate them too much; because it's already big step forward for me. :)
