Sketchbook Moment

Here's a tiny look at a personal project I'm working on. This koala guy looks a bit cross, with that dark line near his eye in this initial sketch, but I'll fix that and make his face sweet and happy. I'm completely in love with the sketch stage. As much as I love color I get anxious with adding the first little bit, but once I get going it's ok.  Do you have those anxious moments too?
