So far I have the head texture and I'm not sure what body part I should get it for next. What order did you guys get them?

Well after i got the head texture i started with the hands and biceps/triceps etc. then i went to the legs.
the order dosen't really matter it's just about getting all of them.

try to get a tricep or either a bicep. i got bicep first after i got the head

Depends on you. :3

I started with legs because they are a bit more prominent then other body parts.

start with hands and foots then the legs and arms and at least the torso :3

I'd get the thighs or legs next because they are the largest textures in the whole body, and without them, the tori looks like complete crap.
But it's ultimately your choice.

I would say, get the Legs and thighs, then the biceps, triceps, then the hands. Then get the torso parts last.
