Original at right obviously. What do you think?
Epic win. Very nice work.
Beautiful!!!! Well done and thanks for sharing the vid.
I agree with this statement completely, very nice work. Unlike most of the other fan-based P2 recreations, this one holds true to the P2 spirit the most, in that it actually looks as if 100 or so years have passed
I can see you worked very hard on this. A job well done! 
Did you know that American English isn't even my first language? It's actually [spoiler]British English[/spoiler]
Released maps of note:
[spoiler]Versatile Diversity
L-Circuts[/spoiler]
Update:
May change the sign to give off a blue glow like the other map for consistency, but it will be more subtle here. (maybe make the sign dakrer for it to make sense) Just realized you can see an easter egg but it isn't easy to spot...
Crits/comments/etc. plz!
*Inner Orgasm* Ohhh man I love those textures!!

Very, very good eye-candy here. However, to me the chamber sign looks out-of-place in its current look - you know, everything is so old and broken there, and the sign looks like new 
(percentage calculation sphere self-test failed!)
108.1% done, -8.1% remaining...
Released here!
All maps for Portal (1/2) worth playing are mirrored here.
I would add some wear and tear but I want to refrain from reskinning it. (for various reasons) I wanted to add broken glass decals, but the decal tool makes decals huge (decals cannot be sized)and I can't get the overlay tool to function on models since it is for brushes.
Also, in the first P2 trailer, the signs they showed don't seem damaged at all visually; they even start up normally. (check the part with Test Chamber 7, look at the sign)
Just to let you guys know, there's no puzzle changes, just visual eye candy, and a new soundscape. I may add a seperate BTS area alongside the test chambers, but this is only if I finish my BTS texture making, and figure out a way to get concrete into the BTS areas since the ones in P2 they have shown are all metal. :/
Use overlays.
Overlays do not function on models, I have tried, as I have said. Further proof is that the overlay entity asks for which brush faces it is on, not model faces as well.
Update:
This new, clean bit may/may not stay depending on feedback to it, since it goes from dirty to clean. (the walls do suggest, however, that it is being rebuilt.) hard to see but In this pic I put it in; there's a custom fizzler model both where the fizzler is and (for better viewing purposes) on the middle-right of the pic.
