Staying “ahead” of trouble (Illustration Friday)

I've been drawing a lot of rhinos lately, so for this week's illustration I thought I'll include a rhino in it somehow.

I spent a lot of time tweaking the colors on this one and finally ended up with yet another yellow palette. Also, I created some custom brushes in Photoshop. I took my sponge and dabbed some marks and scanned them and made brushes out of them. I plan to do more digital sponge/cell looking paintings.
