Photoshop Madness

I've been doing a little painting in Photoshop, mostly playing with different techniques of rendering starfields, but also tuning up some of my texture painting skills, with an eye more towards realism. Specifically, I've been playing around a lot with painting realistic wood grains.

Here's a space scene I recently painted. 90% of this is Photoshop. The little bitty starship in front of the gas giant is from 3ds Max. It isn't textured, but from that distance, I don't think it needed to be.
