How about seperate builders also? Then people can merge those rocks into 1 larger one. It allows much more variety. prop_statics are cheap to use in a map so if there are 10 more rock models which can increase the detail alot then its welcome.
The all look great!
I have to say though that #3 and #4 looks slightly like clay rather than rock (shape wise, not texture). Could use a few more sharp edges like those seen in the last picture imo.
ps please try and make them use one texture per skin if at all possible!
The existing 005 rock is much moreso than his new one... it even has two small round rocks at the base.koth_penisrock
