The greeby bits remind me of Peter Reid’s Exo-Suit model (the one that got turned into an Ideas set). Great color blocking, such that even a really boring color scheme on paper looks good, good shaping… honestly this is more impressive to me than a lot of what the “big league” MOCers have been putting out lately. If I had any criticism to give, it would be to work on some of the sharp 90 degree edges that the system bits give you. The inverted pieces on the chest in particular are where this is most evident.
