I love the "Shiva" related characters who have multiple hands and your concept is no exception.
I also like the fact that there are more eyes than usual in this character. Although I think there's still room for improvement in the placement of the eyes. Maybe they can be place more in a triangular-net form? Not sure but that's just what came to my mind.
I know that you're in the "Villain" team but my first impression about your character was "aw how cute". I'm not sure if that's what you want as a villain. I somehow know the reasons; Big eyes and big head... these are mostly used for friendly characters. Maybe try to scale down the head, make the body bigger, so it looks more evil (it is all about proportions). The rest of the forms are great!
One last suggestion... How about making the main eyes white and give the iris and the pupil to rest of the eyes?
