exercising the No.2

I was playing with my daughter on the back porch a few days ago and noticed the way the sun cast a shadow on this fake plant. On a whim I thought it would be cool to time myself and see how quickly I could knock out a sketch that actually looked complete. This took approximately 15 minuets, maybe less since I wasn't following the clock that closely. I'm going to keep doing these drills only because of the novelty factor. I'd like to be able to render a sketch of medium complexity in under 10 minuets.
