His face could be a little longer. It's too short and round for Mulder. Very nice overall, though. This must have been a very tough pic to draw and must have taken hours.
I think that this is the best piece of work I've seen of yours yet. :) I really like the fact that you've tackled a really hard picture to draw. And it looks great! Wonderful work!!
I must say, you have potencial ^^ keep on with practising!
