Sounds like a bunch of fun media to work with. I've never tried airbrush though. How do you like it?
Airbrush can be a challenge, but to get that look, it's the only media to use (at least in the traditional world). The only real drawback is the clean up of real airbrush. So as often as I can I use the copic airbrush system. Similar look, much less set up and clean up. rok.
