Seems less effective
I don't know why, but this reminds me of the guy on the Monopoly box. Except in color, of course. This one kind of confuses me because the person is not depicted with a weapon as they were in the previous level. Then again, I suppose that bare knuckles would deliver more pain than a boxing glove. Granted, I would nothing about boxing or anything like that, as I'm just not interested in that stuff. I like how the guy really looks like he's ready to fight.
You got the shadow and shadings really well done in this. While it isn't the most detailed, you get a good sense of how his shadow contrasts with the rest of the picture. It's more authentic when there's no background. Sorry to be the first person to not give you a 10. It's still worth seeing, because it's simply a nice art piece.
