Captain OP, im afraid what you have here is only warlord class.
youre gonna have to think bigger if what you want is imperator..
as a fellow mechanicum enthusiast, you may need to expand your horizons or simply settle for miraculous might of the warlord class.
happy building and well done so far.
Edit: felt like adding some constructive advice.
for your torso and other large forms needing bulk and support. i recommend a building material named Extruded polystyrene, aka blue polystyrene or pink polystyrene. is High density and wonderful for large shape making not at all like cutting and shaping a block of white compacted styrofoam balls.
extruded polystyrene is a building material for houses and construction and available from many hardware places.
