I had a quick run through yesterday and I really like what you´ve done. the atmosphere and the amount of detail is really amazing. I think this is one of the best custom maps for this mod I've seen so far.
nonetheless I noticed some things (as always) which you could improve:
- is this grate some old half life model? It looks a bit out of place. I´m sure you can create a better one with some brushes and high quality textures.
- this floor also has very low quality. make sure you use some high quality ones. if nothing seems to fit, search on the internet and add your own ones.
- same thing with this ugly shutter here. compare the quality of the shutter with the wall and you know what I mean.
- every mirror looks the same -> makes me sad
- boy, these glasses are vvvveerrry strong. do you use bulletproof glass? ;P I need 4 shots with the silver pp7 to break them. that's a long time. I personally prefer glasses which break immediately or after 2 shots. it creates better action.
- I feel so lonely in these empty areas! I would love to see some tables with computer consoles.
- this fence confuses me.
- these pixelated walls ruin the beautiful computer room. in hammer editor there is a white carpet texture. use a smaller scale and it should be perfect.
-in the cavern area the wall texture changes from horizontal to vertical. make it all just vertical, it looks better.
- try to avoid models/brushes cutting into each other. I think it's not so healthy for the framerate.
- the framerate slows down sometimes, especially in the main room. do you use enough areaportals to exclude the non-visible areas?
