I agree with Max - it seems 'artificial' as in it's very obvious that I was created on a computer. now, depending on the look you;re going for, that might be intended. if not, maybe try less bright colours and maybe some subtle textures to break up the large areas. I'm not sure if the blurriness is part of the decreased size of the upload or if the original map is the same.

I do like the structure shapes and the overall layout of the map, as well as the use of different colours to denote different structures (if you weren't going to do it, you should add a key to another part of the map describing the different areas. A scale-marker will help with conveying the... well, scale!
