when I built her my only goal was to kinda make a moc that had a sadistic look to it with dark colors and painful / torturous weaponry. She’s also my first custom moc to use a 2016 gear function. Getting that tire in there after the waist was put in was a pain but it looks better than a gap.
The red on the torso looks a bit odd, and the Skrall mask seems to clash with the overall smooth look of the MOC, but other than that, I really like the rest of the MOCs design.
I think the concept is good, and your MOCing style is improving, the only elements that’re really off-putting are the blocky thighs. Got to question the lack of white in the torso though, as well as red appearing only there. Maybe use a different chestplate that has some of the white bone elements in it.
