well...
the map layout is really simple. There won't be a good gameplay. But as you said that's a concept map. I don't know what you want to show with this map... Fading (white) textures, or bright colored lights? The combination of both? Perhaps you could built a more complex map where you have a good gameplay on it.
I don't think that this combination of fading textures + lights will be used in any map in that extent. It hurts my eyes after short time.
2/5 because it's "brain-melting" and not that usefull (that would be just 1 point), but you tried to make something new (that's the other point) ;)
i also did a cicept map, some time ago, but it seems as if it's not on quad anymore :/
EDIT: I re-uploaded the file: http://www.quadropolis.us/node/924 that's the map beams, perhaps you can combine that one and your's to get super brain-melting effects ;)
