Welcome to the Guild. A number of us who are accomplished mappers claim to be bereft of artistic ability.... even if you had no graphical arts in your hands, you can get decent results as a technician. Further - I betcha didn't start out very musical when you took up music... mapping too is a pursuit that benefits greatly from practice. So pick a tutorial that seems to lead in a likeable direction, and see what you get.

Mapping has the delightful aspect that often even one's "mistakes" just turn out to be serindipitous *possibilities*. Be bold about posting in a work-in-progress thread, and you'll garner helpful tips, criticism, suggestions....
