Wonderful design! Love the angles and parts usage. The sphere-mounting design ere is great, and I love the utilitarian/mechanical core; makes it sem more familiar and human than the BlacktronII drone. But I dig the BTII drone more. This one has a bit too much red for SPII, making it look almost M:Tronny, while the BlacktronII drone was right on the theme's pallette. But mostly, I dig the previous one because I'm a huge fan of tri-radial symmetry. Makes it seem more alien and high-tek.
