Carved in stone style
It looks like a crazy graffiti with parts of it carved into the stone and parts drawn on it.
I love the dynamic of the flying beans and the plate. You gave the biggest, closest bean in particular a perfect angle to make it look like it's about to pop out of the pic any moment. You drew the beans pretty good anyway.
The face however looks too hard and sharp-edged to me. The hair and ear both seem fine though.
The hand may be a little too big, even for the desired angle, but it looks good apart from that.
The body doesn't look good to me. On the boys' left shoulder there's sharp edge and the rest isn't detailed. It looks as if he does not wear a shirt, but if you would have added some sleeves and some kind of "neckline", the rest would look like a loose shirt. On the other hand, the shading (armpit, neck, etc.) looks good.
But yet again, you used another cool and unique style for it. I don't know how to name it, because monchrome is not a sufficient description. But it definitely looks interesting to me.
