Those remind me of where I wanted to go with my Paradroid redesigns from Paradroid 64. P90 was more organic. I always find it interesting to see if it's possible to stay within shape and/or feel constrictions while still adding... stuff I want to add. Like panties.
You're doing the blocky thing so well, and it doesn't feel like you're trying to get quick results with a bunch of random lines either. I tend to 'cheat' by making robotic shapes organic, hiding functionality and sensible shapes under a mush of indecisive goo. Sorry, I think I've ranted about this already.
One thing to think about is overall shape harmonics and theme. If there's no theme, repeating but changing little shapes, then the design will break apart, like a lego kit built from differently colored bits. All the little shape jaggies also makes the form indecisive and it becomes too much for the human eye to read. I wouldn't say you have much of a problem with it, but I can't help getting a tingling sensation sometimes that you've put arms A on body B.
I like the Left (flat blocks) and Right (bendy tubes) design on the latest sheet. They're both coherent.
Watch out with head placement in armoured suits. It helps to just redline in a quick body in another layer and reposition the head (and suit parts) after that.
Jamen jag tror att han skäms, och har gömt sig. Vårt universum det är en av dom otaliga spermasatser som Herren i sin självhärliga ensamhet har runkat fram för å besudla intet.
