Howdy, kilted, and welcome to the forum.
In regards to what you're looking for, the first thing I would suggest is to look through the Dungeon Mapping sub-forum and see if there is something in there that shows the kind of style and detail you are hoping to achieve. From there, it's a matter of determining if your collection of software (gimp, paintshop, inkscape, etc) is capable of producing those results or if you'll have to look for other means. Another good section to look through is the Tutorials sub-forum. There are dozens of tutorials there that span across several applications. Lastly, Redrobes put together a keyword index that might help you narrow your search ( http://www.cartographersguild.com/ut...word_Index.htm ). If all else fails, you can try the Mapping Request sub-forum.
