Gorillaz?
This piece looks like a cross between 2D and Noodle of the cartoon pop band that has been going for some time now. I think that there is some sort of influence here and it was kind of a shame that either you haven't noticed it or just haven't acknowledged it.
I think that the whole piece is a little let down by the background, or lack thereof. You need to have something going on there, just to add some life and detail to the main piece. Perhaps just a scene where you can see the front room of the house, or something that looks a little domestic, as opposed to the stale effect that this beige background currently gives. Of course, focus does mean that some of the details there needn't be as sharp as you have for the character themselves, but you would certainly enhance the picture itself by adding to it just a little.
