The map seems like it'd be a bit small for a match, and rings are awfully close together (and some aren't tagged Float). The invisible FOF over the flames also seems kind of silly, as players would expect to run into the flames and get hurt, and having more than one of certain weapon panels (as well as the dozen or so WRMs in the map right now) are pretty bad for balance. The map also seems a bit dark to me.
That said, it's not bad for a first map. There are two big issues keeping this from a release, though; you're lacking an SRM, and I couldn't seem to find an Infinity Ring in the map anywhere. If you can fix those (and maybe make the insides of the buildings a bit wider, so they're not so cramped), this will be release-worthy.
