Open question to DS, Spitfire, etc

[Reincarnate]

Any chance of a step-by-step tutorial (or even just a video)? I am really interested in developing my art skills but I'm just dumb ignorant about the techniques, especially where coloring is concerned. I can pencil-sketch things, but translating it into anything past that is beyond me. I really like the art you guys put out and would be a lot more comfortable investing in a tablet if I knew it wasn't going to go to waste.
