A word of advice about colouring, it's really about understanding values. If you have good values in your image (values are what you see when you look at grayscaled images), then it almost doesn't matter what colours you use. Just blooping on colour does teach you things and might be a good approach, but eventually, you will notice that good images are usually separated into 4-5 "main" values.

As for anatomy, be sure to practice understanding and especially proportion rather than copying images to "think" you've gotten it right. Chances are you haven't, and even so, you may forget it soon.

You can always get some of the free Loomis books. The figure drawing one is great:
