I also played my way through the map - I also got killed when I jumped into the sewer, but that's the only serious bug I could find. I've included a zip with some screenshots.
Gameplay-wise the map gets pretty hard at times because there's not much health lying around (especially the sewers and the street area after that are hard). I personally don't mind the challenge, but some people might the lack of health a little frustrating.
Overall: good map, and an improvement on the older version. The biggest improvement was the lightning, it looked really good and gave the map more depth.
