I large improvement to your previous maps, for sure. Still not one I'd put in Trem 1.2 or anything, but still a large improvement. Nice job, get those BSP's right, get the performance issues fixed, and take out some random places, and it could be a playable map. That's a fair bit of work, though.
Also, what grid size are you mapping in? It should be 8. I prefer 8, anyhow.
