Pretty much like everyone else said, it seems unfinished kinsei my man, it has alot of potential though i think you should finish it sometime. i Like the massive wings on it, its given me an idea of a dragon picture i should do.

Great dragon lineart, can't fault it. It's a shame that the overall image just screams "unfinished!!!" for me.

Thick lines

If you were for lines only maybe thicker lines around the dragon would of made it pop better for us to see. Oh and of course that one thick line on its right wing be sticking out like a stick.

okay

Nice drawing, his foot looks a bit mangled but otherwise the anatomy is nice... I strongly dislike wingflaps on the front his arms, but I guess that's just opinion. The head of the dragon isn't the strongest spot; his lower jaw is probably too big if we're looking at him from above, but apart from that the head could have a bit more character... some spikes or whatever; it is after all (one of) the most important parts of the dragon.
Composition wise I'd have created a lot less space behind the dragon and more space in front of him; that way the viewer can see what the dragon sees, makes it a bit more interesting.

So evil!
