Oh gosh, I just accidentally deleted a super comment, and now I'm sad. This one will not go into as much detail as I'd like, because I've already been typing for ~20 minutes, and I really want to go work on the map a bit.
LightningSpikeI feel like the wood you made spire out of looks really out of place in terms of the whole badwater design scheme.
DeepYeah, it should've been a big concrete pillar, with stairs around it.
MangachuIt looks really ugly honestly, if you try to make something like the process spire with those the same textures it would look better, if you also plan on using this spire i'd recommend adding something on the ground, it looks really bland and empty when we pugged it
MerchantYeah a bit. Badwater is like Process but a lot more rocks and dirtiness.
I understand all of your concerns. However, I'm going to try to make a case for the style of spire that I chose. Take a quick look at pl_badwater:

You'll see how BLU has to essentially push the bomb through their "base" to RED team's "base". Notice BLU's building style is very concrete and generally well put together, while RED's is much more hastily made, wooden structures. This comes with the goofy backstory that the TF2 world is based around, two companies that fight each other with paid mercs. There's obviously a bunch of back-plot, but there's no need to get too far into that. BLU team (Builder's League United) builds things well. RED team (Reliable Excavation Demolition) doesn't. Because BLU needs to capture points in their own base, it's pretty safe to assume that at some point in time, RED took over BLU's base and built up rickety, make-shift control points (as RED does).
I didn't just throw in the gpit spire all yolo-tastically. There was thought behind it. All this said, if enough people dislike the final product, I will gladly change it.
I'm being called to ring, I'll be back in a bit to post the rest.
