Advice and motivation we have a plenty around here. If you want help fleshing out your maps this is THE place to be. We have a tutorial forum as well as a WIP forum (that is Work in Progress) where you can post the maps you are working on and receive all kinds of help and have your questions answered.We are a friendly bunch so you need not fear for someone knocking your work. One of the main reasons for this is that we have ALL started somewhere with maps that might not be the best, but have grown in skill through this site.
And finally, Welcome to the Guild, the Mappiest Place on the Web.
