Okay this is my thought process:
More tits or less stilettos? :S
On a more serious note, it's interesting to see how the head and torso are masculine while the posture and gesture and lower body are cleary feminine.
In greek mythology, there is the hermaphroditus, which is both woman and man.
I'd also like to think of this in an "above sex", ancient, powerful sort of way. Although its fat hips make it look like a fat little manwoman, trading that power for hilarity. But I think there's really a lot in this piece. If you could somehow make the legs different... hm.
Now I have to think of mewtwo, the belly, the tail, the neck, the thing behind its neck - there's lots of things they have in common. Mewtwo looks powerful because of its pose and because its feet are larger, suggesting muscle weight.
Okay, back to the legs: Maybe more legs? two more which go behind it, facing backwards (like lionfeet at the legs of a throne)? A lower angle, giving her a sense of weight (you shouldn't think you could just blow her away by breathing out too hard)? A less saturated color, removing that pinkish I-have-fat-legs feeling? Thinner legs that match its arms?
Also godesses have minions, especially snakeish godesses! Give it some green snakes that slither up its legs? In a cyclone sort of way, if you know what I mean? One snake could crawl along the godesses' arm, in the way snake summoners have snakes crawl along theirs.
I really think this... thing has a lot to go for it and a great potential! The colors of the head, torso, staff and tail are great (!) and the shading for the finished parts looks really godess-appropriate. It has that distant hawk "don't move, food." sort of gaze. Give it some more weight and nobody can resist it!
