Nice overview. It would be great to see a release in some form, even if you just bung an fy_ in front of the name.
I agree with RD about the lighting, the overview makes it look a little flat. If you are stuck with what do to to improve it then have a browse through some of the of the finished/WIP map threads here on Mapcore. There are some great examples of nice lighting on show in many and I think it would really help lift the atmosphere.
