How thuper! Glitz, glamour, fashion, fame! I'll have them decked in rhinestones and sequens XD Of course that's just a joke and I mean no offense to anyone, but I could give groovy a shot
I like the elf form. I picture them like that as well, lithe and graceful. Height can fluctuate of course, but I mainly picture them as relatively tall and the men still rather muscular. A body that would be in between the two male forms you have drawn, the elf and the human, not super muscular but not too lean either.
