Neutral! Can use some more detail on the walls. Also, The part where the ladder parkour is, you can easily just go on the wall, and jump onto it, then boom, ur at the end.
No support. Just work on adding cool little details to it, and fill up the space you have. Don't just make dark rectangle/square shaped rooms. I understand you guys worked hard, and I believe it will be great once you put a little more time into it! Also, if this is your newest & most improved map, please tag a mod in your other two and request them closed.
