Walling size 3 ramps is quite difficult for Protoss and Zerg, as they cannot wall with 3 buildings effectively. You can place a 2x2 footprint or a doodad towards the white crates to fix this.
Both thirds feel a little bit open, not too much to cause horrendous problems, but it might be fairly difficult to defend the triangular one effectively.
You might be able to alleviate this by moving these rocks here, or making that ramp completely blocked off, so armies cant easily move between the two pathways. https://i.imgur.com/8OwViRQ.jpg
You could make this lowground connect a little to the metal above it, so reapers meet eachother, this just saves annoyances in TvT. https://i.imgur.com/oFhQS9X.png
An alternative might be to make the distance to travel around longer, such as making this area stick out more. https://i.imgur.com/ncgEzSu.jpg
I think the Zhakul'Das cliffs look odd along the outer border, you could try using similar-colored fog to mask the hard transition to the abyss, or try placing plants/bushes/trees to hide it?
You could also use snow drifts to have the snow blend through the different levels, like here https://i.imgur.com/oSrOa2q.png
