hmm. I wouldn't say its over cluttered, and (for me, i got a very good system) theres no problems at all with the gameplay. No lag. Here are my thoughts
OK, overall very good. I like how all the clutter is "organized" clutter. It dosn't get in the way too much..
1st Pic = I like how you have alot of freedom in the map. One of my biggest pet peeves is when map designers put blocking volumes in places you should be able to get too.
2nd Pic = This might be my only critsism. Your map is kinda bright. If you go close to these areas (in the pic) you get blinded
. Maybe tone down the lights a bit.
Other than that. good map.
