If you like it, keep it that way.
But since you asked for opinions, it does look unfinished to me.
(Perhaps if you just finished off the head more?)
I think if you're going to do a piece which has that incomplete but complete look, you need to plan to do so in advance, so that it balances properly and looks more intentional.
It's a lovely piece of work, and I would like to see it go all the way.
But that's just my humble opinion! It's YOUR work, and if you think it's complete, it's complete!
