worked on this some more this morning. I'm pretty sure I'm going to go with the trees on the right hand side. I think they give more flexablity, where I can scatter a few trees here and there, to help balance out ares. I'm also probably going to go with buildings for marker, over symbols. I darkened the oceans and seas. Not 100% sold on that.
I also figured I'd work out the text now, so that as I move forward, everything fits together.
Now that I look at it, I'm probably going to redraw the lines around the cost to be more natural looking. They are starting to look to stiff.
as always, feedback is welcomed.
