I think Leotaku was right, it would look a bit better if it was a little brighter. The drawing is very good. I like how you did his goggles and hair, nice shading, too. :)

Wow....there's no other way to put it...just wow...This is amazing work! ^_^ I like it so much awsome job *give you cookies and glowsticks*

Would've looked nicer if you could adjust the levels or contrast to make it brighter, but the drawing itself is still good. Nice expression.
And, thanks for visiting my page. :)

Ooh.. nice job. I love the goggles.
