Really like the open area, not overdetailed, nicely playable.
Though you've got quite a couple of mountain borders unfinished there that break it a bit.
Also the bridge on first pic makes no sense to me, if you want an impassable terrain on ground floor simply connect those two sides together with a mountain.
The bridge looks very weird and unrealistic compared to the rest, while all those pillars just make it look rushed.
Also the left side of the bridge is suddenly a straight line which makes no sense, when the other side is obviously not flat, if you're looking for a place to elevate that's easily doable with a mountain and it will look much better, imo.
