So back in the good old days I use to sketch, a lot. And I always wanted to take those sketches and somehow make them all "professional" and such in Photoshop but never had any luck?
So here's a couple examples of old sketches I would love to touch up on:

Currently I have a Photoshop CS4, if anyone can point me in the right direction or even just a place to start it'll be greatly appreciated
