Oooh. Good points landorl and ravells. I'm gonna be working on this one in the coming month as I have a few other maps I'm working with right now. As for the technique..yeesh I dunno I kinda 'winged' it to be honest, just using a ton of brushstrokes with a very small range of colors. I do know I used almost all of the wet media brushes. They have a set opacity as default but I believe I lowered it to about 20-30 percent.
Thx for the positive comments guys!
