Well surely it helps to be detailed, right? Like the difference between an orange map and one with moderate detail (not necessarilly good detail vs. spectacular detail).
It really shouldn't, but yes, the best looking it is the better. But still, people should vote based on their gameplay experience only. Not aesthetics.
I've never used Ustream before, but now I'm having fun-times broadcasting mapping.

I dare someone to make a TC map in 72 hours.
I beg to differ. You can't mandate that users only examine gameplay, because aesthetics will be the majority of what they think about later.
Um, is it allowed to use swamp pack props? or?
Custom content is allowed, but only made entirely by yourself using your own resources, Valve's content or if is available to the public as of now (Made by someone else).
Detail serves the sole purpose of providing eye candy - if you put hazard strips around a capture point that's not detail because it serves a useful gameplay purpose. If you add red/blue arrows indicating direction that's not detail because it serves a similar purpose the hazard strip did.
Detail would be something like a smoke stack on a roof, but even then if it drew the player's attention towards and important gameplay space (something like 'This way to the middle cap point!') it could be argued that it's not detail either.
I think "aesthetics will be the majority of what they think about later." is a pretty short-sighted statement to make, considering probably everyone who participates in this contest are in it for the gameplay primarily.
