Well, welcome to the Guild. The best place on the web for learning mapping techniques.
If you have already drawn some maps, post them up in the Work In Progress Forum and we are more than willing to give friendly critiques and suggestions as to how you might improve them. I say might because the maps are your vision, and we can only suggest, and it is up to you to say what works
If you need inspiration as to ways of doing maps, the Tutorial Forum is a great place to pick up tips. For styles, you should check out the Finished Maps and Cartographers Choice forums for what can be done and how they did it.
The best way to learn is to post the maps you are working on and try out some of the suggestions that are sure to come.
BTW, we need more Hand Drawn maps!!!!
