Hello, and welcome to the guild! The best tip I can give you is to start a project, even a small one, say a little village or even a farm, and then post it. Hand-drawn or digital, you'll get a better sense of where you're going once you start! There are lots of tutorials and the ideas in a lot of them aren't tied to digital media. I regularly plunder the maps here for ideas on how to represent various things. Enjoy your time!

cheers,
Meshon
