I was thinking the same thing about Deja Thoris, I mean, I didn't expect the Martians to be naked through the whole movie, or even close, but yeah, everyone seems way to heavily clothed. Maybe it's different through the whole film. Depending on the scene, I'm sure Carrie Fisher wouldn't have worn a metal bikini for a whole SW trilogy, (But who knows, Lucas keeps making changes).
But the tharks and Carter's hair seemed ok to me. They don't look like they have less muscles than the red martians or humans, it's maybe it's the height, that creates an odd perception that they are skinny. They don't look much different than they were portrayed by Michael Whelan, on the series I read, and John Carter's hair seems long too...
