Actually I like tha map.
I played it with some bots and it worked out fine. The layout is supporting ffa-action, imo. It feels like you´re always running ahead, while your actually running in a circle. That´s pretty cool!
The detail-level is also good. I would add some light-sources and maybe some broken walls here and there, though. I recovered some 'bad bits', which should be fixed. You might go over the whole map once again, keeping an eye on those little things. :)
The only weak point is the watercolour. I know it´s supposed to be blood and actually that´s the outstanding theme of the map, but it looks a bit over the top this way. I tried some different colour values which make it look more 'realistic', as far as this is possible... :)
It´s up to you, but try something like this:
/watercolour 25
It´s more transparent and supports the 'gloomy' atmosphere better, I think.
Keep it up!
