Elf man Line Art

Ok so i know its a lil ruff around the edges but, its getting there eh? better then some of my other linearts. Not to mention the fact that this was done at 2 in the morning.. (my letters look like a foriegn language right now kinda like korean..) but yeah, he looks pretty ok, i mean my proportions are a little off and his head looks a lil weird but heyyy. anywho if you could all give me an honest opinion on what i need to fix that would be great! also Free to use so long as its linked back to me! Id love to see how someone turns my very crappy art into somthing amazing! (side note: this is only my 3rd of 4th attempt so far so its noob like)
