Here is my feedback, I hope that it is of any use...
First of all, I though it was quite a good map
It connected well, the lighting was fine, as was the bot-pathing and it wasn't too hard to learn.
Sizewise, I played it with 7 bots and that seemed alright (4-10 would be the ideal range IMO).
The layout was alright as well, although I do have a few gripes with the staircases "just being there" if you know what I mean. Perhaps if you decorated them in some way with extra brushes (eg pillars) but that could push the frame rates down.
I've got an Athlon 550 with an overclocked G400 and managed 45-50fps (good enough for me). There was some slow down in that corridor with the cob webs which could cause some problems though.
A couple more recommendations, if I may:
1. There's a spawn point right next to the power-up which isn't advisable IMO (although the jump pad and lava pit are good ideas). Is there a RL on the levl above it? Placing one there would add a dimension of risk to getting the power-up.
2. There are HOMs on the apexs of the curved surfaces.
3. There is a spawn poinnt next to the FC which could lead to spawn-camping.
4. I hope you plan to include a screen shot
5. I also found that you could jump out of the arena with the anti-grav boots. Are you going to put a roof on it?
Other than that, top effort and I would give it a 7.5 in its present form. I'm looking forward to an updated version... Hope I was of use.
PS I really liked the statues. If you made them
