This is a nice piece of work, but I wouldn’t be so fast to call it finished.
A few things:
I think the whole piece needs a little more depth. At the moment it’s sort of got a wierd Japanese silk painting vibe about it (perspective wise), which is kind of nice, but I’m not sure if this is what you intended.
Also, in my opinion, the characters and the environment aren’t marrying as well as they might do. It looks very much like the girl especially was painted as a seperate piece and then pasted into this composition. I’d work a little on resolving some of the style differences.
As well as that, I think it could benefit from a little more reaction / interaction between the characters. Something that would tell a bit more of a story. It’s pretty obvious what’s going on, but I think it might be helped along by a little more indication of her reaction to him and vice versa.
That’s about it. Hope this helps!!
