rip your life
I'm fairly certain I saw "Pearl" before so I'll just talk about your selfMOC.
...in comparison to the MOC below it, it falls short of what you can do. Too many textures and different types of pieces floating around. It reminds me of some of the worst MOCs that I've done recently. I'd suggest redoing the armor so that it uses the same "groupings" of pieces, as the Metru-era pieces on "Pearl" that all come from Metru-build Toa and are thus made to work together. If possible, mixing in some CCBS in Windfall could improve his look.
