Usually I don't recommend these discussions going on but amt got nothing better to do... Elspec doesn't give any good hints, he doesn't show u his solutions to problems or anything, so with him we can't speak about constractive criticism (depends how it's defined). He simply says what's wrong at map in his view, nothing more, then it's up to mapper to find solution. It's a bit ironical but I usually agree with his bad ass critic.
About map again. Theme is awesome. Okay agree with vig that it looks a bit like his. About maps I know by Virtual TT nothing is even near to this.
Dunno about gameplay in htf, but I kinda don't keep it practical idea to make same map in many gamemode, it probably works good at all of them but emm I can play this map once to feel atmosphere but there isn't the hook to keep me playing this.
