I think you should ditch the guy and go with the abstract look. The bg really looks awesome but the painter itsel kinda bring it down, mainly because the brush doesn't really blend int, makes it look a bit fake.
Yea I was gonna turn the brush into a sharpie but how I had to placed before it would have looked like a stick in his hand.
the brush and person was hard to notice, so far this looks like a wip. the vectors could use some work, and it just needs more.
