I'm not a geographer, so I'm not too attuned to what is unrealistic when it comes to rivers and such. Thanks for the information.

So far, the mountains are one texture with an Emboss/Bevel over it, colorized, and white airbrush underneath for the snow. I'm getting ready to post another map I did that will be used for a fantasy game this weekend. Please take a look and let me know what you think.
