The bevelled look was kind of a "that looks neat" kind of thing. So, I'm not too attached to it.

I agree with the rivers comment. I'm having issues getting them to 'look right'. When I do them, they seem too smooth. Any suggestions? I'm just using the eraser tool with a Wacom Tablet, if you're wondering.

Also, I like how I did the mountains, but they're just not quite there for me.
