ok. here's how these things are painted simple as possible:
2. flat colors
3. render it out (i use a set of brushes in photohop that are good for the way i use the wacom)
4. tweaks (like fuzzy wings or little specular higlights or colors)
i don't mind sharing the process, but i always recommend that in art there are many ways to make things look cool. Once you are comfortable in a package, explore to find a way to make your art look unique, since so many of us are doing it.
