Sorry mate, gonna need more details, like where are you starting on the map and what kinda mission you are supposed to do.
Lets take the Second for example, cause I think it pops out the most. If it like some escape mission where you start in like the east and need to make it to the west, with those chest up top being added bonus for taking the risk, it could be great. However if it like a route mission where you gotta kill everyone and one side finishes up but can't help the other side cause I notice that the top does not connect, It can border on annoying at best and frustrating at worst.
Do you at least see what I am getting at, how these details can change the (very subjective) enjoyment of a level?
