If yo also create Pandaren female model`s do not set them Blood Elf Female Try change animation set to (this theoretically) Dwafrf Female animation set or try goblin female anim. set. B`coz look`s ugly. The pandaren (female) have hypersthenic body proportions and Blood Elf female - asthenic.
I hope, you uanderstand, what i mean.
PS. Try change animations of that model to anims Tuskarr or Dwarf (male)
