You're enthusiastic, which is good, but I'd suggest improving on your skills by focusing on one skin
before moving on to the next.
If I were you, I'd rely more on freehand, by starting on the armor, which seems like CnP'd from a picture of a WoW model, then moving onto the face. I'd also set up a thread on the
Texture & Skinning section of the site to show progress, and get more input from more dedicated 2D artists than myself.
