I recently got Photoshop CS5. And I've never used photoshop before. I drew a picture, inked it out and scanned it to my computer. The problem is I dont know how to color it on photoshop cs5. I need help with:

layering
coloring
how to make flesh
clothes/shadows
hair
eyes.....

basicly everything TT.TT

I would really appreciate anyone that can help me.
