This was a very beautifully done remake, and gave it a totally different and richer atmosphere.
There are a couple spots that are very pretty, but quite bright if you're thinking about a competitive game on it - which, to be fair, isn't necessarily the highest consideration considering that metl3 is a very mediocre map compared to what we have to play ffa on now, but still could be considered. These are some of the spots I thought were a bit bright and could be toned down.
In case it's not clear, it's really just the teleport here that felt too bright.
The far wall here
and the floor under it here
Other than that, amazing job, I'd much rather play on this version than the default one.
