With compliments of CFG on posting the tutorial on his forum: Christian Friendster Group -to Filipinos out there, pls come and join on this forum thanks.

That's a nice beginner tutorial right there~! Seems simple to understand all the basic elements.

I have a few useful photoshop tutorial links that would deem useful too:

Deji-chan's Soft Colouring Tutorial
Deji-chan's Hair Colouring Tutorial
Deji-chan's Generic Colouring Tutorial
Deji-chan's Palette Making Tutorial
(Can you see how much I love Deji-chan's tutorials? XD;; )

iruka-loves-kakashi's Masks and Layers Tutorial
iruka-loves-kakashi's CG Colouring Tutorial

If you want, I could post general drawing tutorials, because photoshop can't do magic on everything.
Most of the outcome comes from what you can DRAW.. and there are heaps of nice tutorials out there that can help guide you along. *still in learning process* ^^;;
