Ahhh, but you err in presuming all the goodness here comes from ace artists and master mappers. Not so! One can come up with presentable & serviceable maps by following directions and attending to detail. Even the old "can't draw a straight line with a ruler" excuse won't hold water, since maps seldom need straight lines :-). Seriously - find a style you like, software you have or can obtain, and work through some of the Guild's tutorials. You'll surprise yourself. Can't beat your own work for matching your own needs and druthers.
Welcome to the Guild!
