i'm not trying to be hostile, it just irritates me when people post about art related things with no idea of what's involved and then are surprised when nothing happens. i've seen it happen enough to know that threads like this either never go anywhere, get huge and then die when nothing happens, or start to go somewhere and then turn to shit.
you have no fucking clue how much work it would take. i have significant modeling experience (i never finish anything though) and passing modeling and texturing experience. months of work here for one person full time and the quality would likely be poor.
