Unless that is a minibase used for some specific reason and soon to be abandoned, you are going to have some problems.
As noted above, log trolls will make mash out of your base. Their reach is 3 squares in, on every side. Plants and trees are safe but any player make building piece is not.
No garden room. Where do you grow food?
No stairs to top so you just have to hope their little blue faces pop over the wall so you can shoot them. With no stairs you have to jump and use half your stam in case you have to get out of Dodge, Basically you have trapped yourself in there.
That fencing makes great walls but you can't see out. If you have regular walls you could put glass in the windows so at least have some view but you have open chimney so it's all moot anyway for da bats.
