Bionic arm Medical Arm reskin WIP

About this image

So decided to do some reskin modding of the bionic arm in TPP. In some art of MGSV concept art, there was meant to be 4 additional arms to what
we already have. One of these being a Medical Arm (probably something
similar to the medical box in PW), so here is a 65% done reskin of it I
got recreated in TPP. Besides the red bits looking too dark and missing a
few extra features, this has came out well. :) What do you guys think?
