So I decided to get back into airbrushing. Picked up a brand new airbrush, paints, and a nice new setup, so this was really just a practice to get back into it. It's actually been about eight years since I last airbrushed, so I was a bit nervous in the beginning, but it turns out it's just like riding a bike. I think the years of pencil portraits really helped with this.
Based on this fantastic reference picture. He just had so much character, I couldn't resist:
I've also got a pencil drawing that should be finished in a few days, but expect to see a lot more ambitious airbrush work from me in the future.
