Greyscale Colouring Tutorial

I've not been able to paint the last few days so I decided to try and write up some sort of basic tutorial on how I colour from a greyscale image.

I'm still learning myself so I find it quite hard to give advice but hopefully a few people my find something of help in there.

Feel free to leave me a comment if there is anything you don't understand and I'll do my best to help out. Also I may do some more tutorials in the future so if there's anything you'd like me to cover let me know.
