Wow haven't seen you in a while!
Just to let you know, it is kind of public knowledge now that NS2TR alpha 1 and 2 have been released, these are basically models and textures (nothing from NS2 tech in there yet). So it is more of an artwork release...
Both released versions are only available to a select few mappers (on the mailing list or something), I'm not sure if I'm even allowed to post this. But some of the DEVS also posted about it on the public forums, so yeah it is kind of public knowledge as I said before
KFDM will edit this post faster then a lightning strike, if I'm in violation of the LAW

Now to comment on your textures
I'm with you on this, 1 and 2 are bland and kind of need more, how do ya say... umph? with this I mean I'm not sure what they are supposed to be with just a metal plate look. They kind of need more defining features to make it clear what they are. I do like texture 3 though, good oldschool NS1 look with NS2 quality! On question though, do ya only have the textures or also the mapping textures (kind of mandatory for source texturing (special effects etc...)
