You're right about the lines, they are indeed made of many smaller ones, although the "hairyness" might also stem from the fact that i haven't erased the underlying sketch all that well. Also, it feels like my hands just can't do long, smooth lines, which is also evident in my handwriting.
Also, curves? I'm sure you mean something that isn't just curved lines, but would you mind elaborating?
@trickbob: I agree about the shading, but keep in mind that it's my first serious drawing on paper. Might still tack on some shading, though.
About the expression, however, that's a bit of a special case: In my little world, dragons are canonically very unexpressive (varying between "grumpy/indifferent" and "going to eat your fucking ribs"), though i suppose it would have been a much more interesting piece if it wasn't so passive.
@Dscigs: Yeah, the red does stand out a lot, i probably pressed too hard with the pencil. :U
Also, if i try to do things carefully, they just end up looking worse, which is pretty odd. I suppose it's down to practicing more!
