Just kidding I'm not very bothered, but doesn't it look like this artist clearly studied how to draw a hand, but didn't study how to draw a piano keyboard? There are two different perspective lines for the keys -- one for the section on the right and one for the section on the left. They don't line up. Also there are no gaps between the keys at all. They're scraping up against one another.

(For some reason I can't select 'html' from the drop-down menu so I can't embed the picture.)

Yeah, they have two completely different perspectives going on and the side with the front of the keys view has the angle wrong. The lines for the front of the keys needed to be at a sharper angle to the top to give the illusion of dimension. The way it is it looks almost, but not quite, flat. They did do a decent job on the shading of the hand.

I didn't notice the perspectives until I read them in the two previous posts. I did notice, however, that there in one too many black keys in the upper left hand corner of the picture.

I noticed that too.
