I am trying to do that thing where you make an alpha map that doesnt look terrible.
- screenshots snip -
Im not fond of the supports, they are too frequent. Other than that i am pretty happy with it.
For the first screenshot, the grates and the material on the barrier (right of the door) look weird. I think grates look weird because it's normally on the floor, so it's probably just me and my stupid preferences. The texture on the barrier probably looks weird due to the perspective.
Once again, in the second screenshot, I dislike the texture for the doorway. It blocks most vision, so you might want to scale it up or find one that reveals more behind it. Other than that, you might want to use a brighter texture to add contrast between the supports and walls. Overall, I love the look of that work. The geometry is spot-on, but that point will suck for when you blockbullet around it (for the splash damage bug). I'd probably brighten up the point to draw attention to it more, but it's probably my dark screen.
For the third screenshot, it's all vertical and horizontal. You might want to vary the lengths or heights of the pillars, or break it up with more negative space and diagonal supports. Once again, you see a texture being repeats, so maybe using negative space would be better. The similar tones between the grate and supports could be contrasted with the supports and the white diamond plating texture (imetal003, I believe).
I love it Zahn, just maybe change things up a bit and add some variance. Good luck with your work!
