That whatever it is behind Wanitama's legs on the second picture makes me wonder if one of these... skirt things (forgot how they were called), you know, the ones Clone Commanders from Star Wars sometimes wear, might look good on him.
Otherwise I'd say he could use som red on the front of his legs and upper arms. And potentially better hips since they look like he can hardly move his legs forward if I'm not mistaken. Also those Mata hand shoulders limit arm articulation quite severely, don't they?
Well, since the Brotherhood Project is cooperating with RSG now, story stuff has to be aligned to work for both projects. Just yesterday I gave the RSG guys a list of short Makuta descriptions to see what their opinion is. Perhaps I'll already get an answer later today.
In general I'd say, changing story stuff is fine as long as I haven't written the Book of the Brotherhood entry, but you should only change minor things/add things, if possible. Changes of Mask power are always possible, though.
By the way what about your other Makuta? Because there are still people around who'd like to participate at all. You don't have to give up your spot if you don't want to, of course.

All Makuta are currently assigned
