well here is one of my drawings of my character, killamnjaro. he is completly hand drawn with a pencil and paper. I am 100% self taught. if you have any suggestions on if is name should be different please say so. one more thing... if you want to see picture a bit larger then follow this link to deviantart.com.
A good suggestion would be to get better before you start bragging about how you're self taught and everything. I mean this is the most polite way, because most people here don't care, unless they worship you for your art.
To be honest, this makes me remember my first few drawings. Just keep drawing and eventually your style will evolve and people will start to like it. I do think that this shows promise, but it needs a little more detailing. Like put some wrinkles in his pants, put creases where his joints are and stuff like that. You can pm me if you want me to show you an example of what I mean.
