Are you striving for a Shakuras Plateau-ish map? If not, you might want to make the middle a bit more open and less choked. Also, I don't like the gold mineral placements, it feels strange with such a sparse mineral line and just a tiny cliff behind it.
I'm not totally serious with this one, at least not just yet. I allowed more experimenting into it than I usually do to come up with something different. I'll leave this for awhile, but I will .. brood on it and the suggestions you give. Thanks
