The posability and stability on this thing is quite impressive.The incorporation of system with the technic is really great, far beyond anything I could do as a system builder myself. The color blocking also is really nice, as is the amount of greebling.
My one, very minor gripe is that the very bottom of the torso seems strangely flat. Although I have no idea if that could be avoided, since I don’t know the inner workings of the MOC.
