Welcome Eurypon! I was totally awed and intimidated by the beautiful artwork of the Guild when I first arrived here as well. I had absolutely no prior working knowledge of GIMP, Photoshop, Inkscape, or any other mapping software. Yet after checking out some of the tutorials, and through the help of many here, I learned how to create a decent digital map. So let this be an encouragement to you. If I can do it, then so can you. My advice, download GIMP and Inkscape, pick a tutorial you like and start going through it step by step. Then throw up a WIP so that you can receive advice and corrective feedback. Look forward to seeing more of you here at the Guild.

Cheers,
