I haven't submitted anything for a while and thought I'd give an update.
A project I've been working on recently is making a model of the classic T-800 arm from the Terminator films.
It's been slow and painstaking, mostly because I've been obsessing over little details in the hand which isn't helped by the amount of differences between source material.
It won't be finished for a long time but I will eventually be building a complete endoskeleton as my knowledge of modelling progresses.
I'll add a link to a screenshot of how much I have done so far.
