I just created my Intro yesterday, and downloaded GIMP last night. I have never used a computer to draw anything before. My maps have all ben pencil and ink with shading I use in weathering Model Railroad rolling stock. I am amazed at what can be done with minimum effort. I have an island that is real, but I am using it for my first endeavor. The island is in the middle of a river. The shoreline is very flat, but about 30 feet back it starts to slope up to like a round topped mound. If you can envision a bath towel rolled up laying on the floor, this is about what it looks like. My question...How to I go about showing this sloped mound? The mound or step-up is probably 20 to 25 feet higher that the river water line.
Thanks,

Benny
