Its already great, I love it. Much better than anything I can ever come up with.
I do have something I need, but its not with this map but with another I am nearly finished with (sorting out bugs and things now) - it lacks a good preview image.
If you want something to do, I need those. It doesn't need to be anything flashy.
You can add these images to a similar logo and add the words "PK Jail" preferably in combination of red, yellow and blue colors (gradient would be perfect starting from red -> yellow -> blue):

If you don't already know, preview images need to be in .tga format, either 256x256 or 128x128 in dimensions. You probably do, just reminding you
