I'm Loving this one...is that the whole pic? 'cuz i don't like how the ball is cut off. Maybe add something to the right, since it's a bit empty, and it'll be a dime, or something close to it.
The effects behind him are outstanding (except the brush or whatever that is is cut off in a straight line, so that doesnt look good), and the text is nice. The ruler thing is unneeded in this wall. One thing, however, is that everything is on the left, which is the side where most desktop icons go. but of course they could move their icons, so no biggie, nice job.
