I understand that the lags may be too complex compared to the rest.The exo-force arms on the armor are to add thickness because of the weird anathomy and the grey pieces near the ankles help to hold it all together.
I get it. I would change the armor to normal blue but I don't have that pieces.
Compared to the human propotions they are a bit off but I think that matoran don't really have them.
Thank you all for the comments!
