I'm not sure if this is an original piece or you used a reference photo but either way it's a really nice, cute drawing that I can imagine being in a children's book or even in a Tim Burton cartoon. The little guy reminds me of "Purple and Brown" which I really enjoy even at my age. Although I do think you should try and color it either digitaly or traditionally because it would add so much to the picture. All in all: I really like the style that this is made in and the drawing in whole but I do think you should color it somehow, it would give a much better vision and impact. Keep up the good work.
