Firstly, Welcome to the Guild, The Mappiest Place on the Web.

Secondly, you have most deffinatly come to the right place to pick up mapping skills. You should look at the tutorials forum for pointers and post your work in the WIPs (Works In Progress) forums for feedback and answers to questions that may arise. Don't be shy, we are a friendly bunch and we do excell at helping people learn the skills, if I do say so myself.
