Seems to me like the upper legs are really precariously skinny. When they were all one complete construction I would think they have a fair amount of rigid strength, however now that you've cut and joined the surfaces, I'd be really apprehensive about their strength. You had pointed out at some point that although the model is poseable, the main concern is that it can be "locked into" a pose. Still though, I wonder if you could provide some additional support along the sides, or even, Shudder, rebuild both the upper legs...

Additionally, what's the plan to correct for the angles of the legs. Given that you cut away two bits and spaced them apart, the angles are no longer flush, are you just going to create a new strip to reform the teardrop shaped thigh?
