Yeah. Usually you would want to make all distances less than 10-11 tiles. Nobody likes to get killed by someone who you have no chance of seeing. Blind kills aren't fun.
There are places which are good blind shooting spots. What I mean is that there is a bottleneck which you can abuse by random shooting from further away. However it's only a matter of taste.
It is also a bit repetitive, meaning that there are basically same boxes everywhere without much variation or theme, so to say.
Other than that, it's better than any of those on your map pack.
