Robbie in the Bathtub

Some of you may have expected to see Robbie in a scene like this, granted his name is a play on the term "rubber ducky".

As typical as this picture my look, it wasn't easy for me to come up with this. I mean, how do you draw a fat-bottomed guy like Robbie in a bathtub? I drew several different angled views before settling on a simple side view.

The next challenge was the bubbles. I was kind of doubtful in the process of making them, but I'm happy with how they turned out here.

So there you go. Well? What do you think?
