Hi there! What's been said so far is great help!
I see that you got new pencils, and that will definitely help.

I think the key thing to remember is to layer your colors. And don't be afraid to experiment! The key to richer drawings is color! Don't be scared to throw some blue shadows on red areas. It's all about contrast and making it work.

I'd also read up on some color theory stuff, that helps a lot. And never forget that the best practice you can get is to draw from life. :)

I hope that helps a little. xD
I'm horrid at advice.
