Try to fill in the holes in the shoulders, and perhaps integrate the Inika heads a tad better. I like how versatile the Inika heads can be, and it's showing here, but it could be better, IMO.
And I'd scrap that torso. I'm just not feelin' it. Scrap the vissie feet, perhaps, then flesh it out some on the sides to cover up some of the Metruan limbs.
