Not bad.
Not bad. Lots of lighting on the outfit, and the use of only yellow is nicely done. I kind of like the suitcase-head idea. The figure is good, but my problems are with the rest of the piece. So much dedicated to text, and the text's placing just feels a little awkward, mostly because of those ray-filled boxes around the words. And, finally, "He's got a PhD in BEING RAD." just feels a little too similar to "He's got a PhD in KICKING YOUR ASS." from MondoMedia's Dr. Tran.
It's a good drawing, I'm just not particularly fond of how it's put together.
