'Twas large, so mainly this is how I'd shrink it. Not really the distances which I think are fine, just the area. Not all walls have to be 'wall thickness'. Some can just be big blocks of brush, then stick a door decal on and it looks like more than just a big block.
Gonna post so I can see images for comments...
Like this first shot, just kill a lot of space with big thick brush.
In this one I'd brush in all the red space, just too much area, too open.
same, make point area smaller, bring walls in, make that sentry platform closer to point. Only a sniper could hit it from across the room, maybe soly. But nobody else can even get close, no cover, etc..
Outside.
I'd fill in all the red, make doors smaller. Turn blu spawn door towards direction they go.
The loop around the hill (not the rocks, but the one I drew house on) is really pointless. Why does anybody need to go around it. You're either red going to A, or Blu from second spawn to B. Around the hill is out of way for both teams. Could put a building on top to close it in some if you keep it.
But the round a bout just lets teams flank each other and/or waste time.
The blu signs should go on forward spawn, You can't go back in forward spawn in Gorge. The signs make red feel like they are past blu spawn when going to A (out of the way anyway, confusing.
The eye/green area denotes how you'd cut down sight lines if you shrink those areas. Takes away a lot of long distance lines.
the thing with the hill in this layout is it lets both teams easily go out of their way/get lost. Adds a lot of playable space that isn't needed. If blu's forward spawn was behind it and they could go over but not around (to left) it might be good. Might also be good just to put the blu spawn in a house up there so they drop down like gorge. You could get rid of a lot of space on the left side there that is wasted.
All the doors are basically way too big, making them smaller will optimize and give better cover everywhere.
I think it's a good layout, the spaces are just too big open. Good for snipes and scouts or engies with that damn remote. And the round-a-bout around the hill is just confusing/wasted space. The times to points seem resonable.
And I didn't get screen of blu first spawn, but like I said in an earlier post. Put a building over one bridge. Make the canal half as deep. It's huge and no one uses it. Block off areas to width of current bridges. Make other bridge almost half width. And I think that area would improve greatly.
