I noticed a fairly pronounced issue last night. Playing on Blue team I noticed that red team players looked very much like blue team players in the shade. There were a lot of situations where I couldn't tell immediately if a player was red or blue, giving enemies an advantage over me. I'd recommend building the map on Skyward instead of Nebula, as the lighting is far better.
I might rebuild it, but considering how annoying it was to complete I don't think it will be happening in the immediate future. My goals with this map were to create a balanced prisoner style map, and also learn what I could do better and plan for an epic h5 Chain Gang. Also, I think nebula gives the map a great atmosphere, even though nova messes up the team colors):
