Welcome to the Guild, Quintus -- your English is plenty understandable. Look around and see a style you would like to try, among the tutorials, and dive right in. Fantasy cartography is definitely a field where you can learn by doing! And if you post some of your work as you go, members will be glad to make suggestions for improvement, or answer questions you may have - we are a friendly bunch.

Do you already have graphics tools you know well, or will you be picking out software to use before any other decisions? Or are your tools paper and ink? Hand-drawn maps have a place here too, even if it takes a scan before we can enjoy them :-).
