Here's some Feedback:
Overall the map doesn't feel all that halloweeny. The most it has for that theme is the underworld area and I found it difficult to figure out how to get there in the first place. The Underworld may be a tad dark as well but still looks good overall.
-Kinda odd to have all these candle chandelier's and none of em are lit
-This box sticks out far enough that I can stand on it
-Missing door prop?
-These doors feel like they get in the way and would be annoying to fight around
-The glass door here feels out of place with design of the rest of the area. The building's old and mostly wood yet it's got these shiny "modern" glass and metal doors
-Perhaps this pit could be a long fall pit like the one from lakeside?
-Weird shadows on doors
-The beams should probably be a different texture
-That annoying bug with respawnroomvisualizers on blu's first spawn
-These crates kept making me feel like I could jump on them to get over that wall, but I can't
-These cables are effected by the wind which doesn't make sense as they are deep inside a building
Lastly, many areas in the map feel kinda big and empty. Both inside and outside give me that vibe and could maybe use a bit more decoration. Also It seems that the fog is the same throughout the map and, while it looks fine outside, it seems a bit too harsh for indoor spaces such as the final point. Maybe have the fog tone down a bit when you enter that area.
