I think this map is good. It has nice layout even if there are some mask bugs which will make you stuck in the wall like 12,35 and 26,9 and some smaller eyecandy/mask bugs (which doesnt affect gameplay for example 65,24 and 8,35).
Iam not rly sure about some eyecandy things. The first this wich catched my eyes were that black towers, they kinda doesnt make sence to me because that mountains in the backround are more detailed than that towers. It should be opposite, I would use some other more detailed ones or make mountains in the backround same simple as towers. Walls on layer between layers 4 and 5 should maybe move a little slower imo. Also i would maybe make solid branches other colored than unsolid, its kinda confusing.
Iam not really sure why there is water, I dont think it really helps gameplay in this case. Toaster PU is good choice imo Bouncers are deadly.
