...the whole miniature in general, a mix of organic and bionic / mechanical ...
civilian functionary type chap sounds Very interesting...
For me, he seems to be channelling a certain grimdark aesthetic, where people get very specialised functional augmentations/bionics with no regard to how they look or any wider utility. In particular, that big bolt through the right shoulder makes it look like the arm would have very limited mobility (I can see it being able to rotate about the bolt in one plane, but not 'lift') - it gives him strength for a particular role/action, but is less generally useful than his original arm. The organic hand at the end of the bionic arm is just plain creepy - I like it.
There're lots of bionic soldiers/toughs available, but a creepy civilian functionary that's not a full-blown servitor - that's definitely a gap in the market.
