Check output of q3map2 for a message like "cannot find model xxx" or "missing model file xxx".
Your fs_basepath is a bit weird, it is /usr/lib/games which is where Ubuntu (or whatever) installs the open arena paks, and that area is usually write-protected from normal users.
What you probably should do is create a local copy in your home folder (e.g. /home/neonknight/openarena-0.8.
and then you can create new folders in there and place the model file in there too.
