My feedback?
Good things: Nice drawing, plenty of detail,
and I can't seem to find any mistakes or things that are just not possible.
Bad things: I really can think of only one: from far away, or if you take your first look, it looks really messy, it takes a while to see what's what. Try working on that.
I give it a nine, as I said, uh, wrote: try working on the messy view.
I think it's nice and I have recommended you for the art portal.
(I'm not scouted yet so I can't scout you.)
