Looks nice. Very nice. I really like the upper legs and the torso. Those wings are also quite cool. An interesting mask choice, though, in my opinion, although I couldn’t say if anything different would look better. It’s not out of place, it’s just … I dunno. Perhaps it just reminds me of the Skrall too much.
If I remember correctly you called the WIP of this MOC a (female) Makuta … there aren’t any spaces left for female Makuta in the Brotherhood Project (also have a look at post 586), but since nothing about gender is mentioned here … perhaps you might want to enter this MOC into the Project as a male Makuta?
Only thing this awesome MOC would be lacking for that is a proper G1 backstory.
