Science fiction/post apocolyptic map tile

[Zanazaz]

This is a fairly basic map tile for scieince fiction/post apocolyptic RPGs/skirmish level miniature games. This is one of mu first, and wanted to know what people think? Is the grid line to thin? Does it need to be a lighter color?

I think the grid is fine, the bright yellow and green should probably be toned down some though.
