wthrasherb, nice maps. I find them quite dark overall. I think this is caused by the white cloudy/snowy parts at the edges. I would recommend changing these white parts to pure black, in order to make them fade completely into the background and emphasise the playable parts of your map. I would also brighten up the map a wee bit. Regarding your floor texture, I agree with Falconius, maybe change to a simpler style? I attach quick examples of what I mean.
