I haven't guessed something new in some time, so I thought I'd toss out some guesses. I think we're still due for a dark themed one, though, so I'll keep my guess on my mule.

I'M GUESSING!...
USERNAME: Suona
THEME: Body mods
pose #1: some cool new hair, maybe some of the different elements, since we already have fire. What if one was almost gas, where it floated about a little (can't seem to put it into proper words, but I can imagine it in my head)
pose #2: I really want skin patterns. Like dots or little speckles. Desperately! Like on the face and shoulders would be adorable
pose #3: we can always use more eyes! And maybe moss or mushrooms growing on the body!
pose #4: Body extensions, like creature type feet and hands, and maybe some tails that are thicker and drag on the ground. Or even melting, like your arms melting or feet melting into the ground
pose#5: Maybe some different types of noses, possibly even snouts or beaks
pose#6: some more awesome skin would be nice!
