Thanks for the feedback, guys. Ultimately, I felt pretty good about the area, especially considering NWN2's challenges and all the custom content that went into trying to hide some of them, but I definitely feel much less good about it after reading your comments.
Why is the area so angular?
The walls are purposefully angular because otherwise the walkmesh wouldn't bake and I wouldn't be able to pull up the terrain through the walls. The ground of the Docks are actual terrain and terrain doesn't like being curved when being raised/lowered. I have some ideas on some ways to potentially help mask this, but I was hoping I wouldn't have to explore these options as I'm not sure it'll work out and they're pretty expensive.
The walls are too "perfect".
As you probably already know, the walls are made out of BCK (as are a lot of things in the area) which isn't the most flexible for texturing. A single wall can have more than 4 tiled textures on it, which makes it extremely difficult to make anything that will look good. It's possible though that my texture map is just wrong and needs more help.
There were supposed to be some extra decals for the walls, but those were failing to work properly in the hak (though they were working fine in Override) as they were grabbing other mesh's materials for some reason. I ran into this issue on BGR too, and I still have no idea what causes this (maybe the hak size is too large?).
Why don't you use the OC walls from NWN (such as the ones from Mulsantir)?
These walls not only do not match thematically (they look really bad in the Docks), but they don't have the right pieces to create the docks too.
The area looks too big.
I very much disagree. NWN2 is not a very fun experience when you're fighting in super-cramped areas (and there's plenty of fighting in the Docks at night), and the area isn't that big. Maybe the screenshots are a bit misleading when it comes to scale?
The ground texture looks too light/not dirty enough/etc.
Yes, I agree. This texture is a first iteration, and I'll need to do some extra work on the color balance of it, not to mention darkening it up a bit. The dirt texture used over top of it will obviously have to change too since it will no longer match in hue.
----------------------------------
I was hoping to not have to create a bunch of new custom content from scratch, but it looks like I might need to. It looks like I'll need to create some custom walls (not just BCK wall textures) and make the Harper's Hold and Thieves Guild as a single mesh too so I can texture them how I want. As for the curvature of the docks, I can maybe used the rounded BCK floor that I made which matches the ground texture to hide the gap between the terrain and the wall. It might look really weird though and the walkmesh most certainly won't work properly.
I can now see why the BG2Redux team wasn't able to finish their mod...
