You got tons of tutorials on the net that explain everything better than I do + you have to buy the programs you are working with so you have to know yourself which ones you like to use + not everybody is suited for this kind of work because you have to have nerves of steel XD believe mee~~I hope that's at least some advice. Type in google "how to unfold" or "how to texture" "UV mapping", "modeling in metasequoia" or things like that. That's all I can help with. What I do in my process I all post in my gallery so I can't tell more really.
