Hey guys...a favour or question for all you guru's.

I've been using CC3 for a while now with maps...but the results have always seemed a little...blah when compared to a number of maps I've seen made with GIMP or Photoshop...

Could someone point me towards tutorials on how to make and create decent looking maps in GIMP? (I don't have Photoshop, or the $$ for it) Any help would be awesome I'm fairly "stupid" when it comes to some of these drawing applications...so a fairly idiot proof guide would be best.

Thanks for your time all!
