A lot of the body parameters are very in-built into the model. What you're see is it at minimum settings.
I've been considering using several models as part of the game, including the older Tasque model that has a much less exaggerated physique. Though I'm not sure if it'll work well with the current animations due to the models scales.
It's still on the agenda though, so one way or another there'll be more options in future.
