Snagged a commission from my good friend Roki (a.k.a. ArrowTibbs). I *love* how it turned out.

@LadySil Ooh, they did a really nice job of conveying the expression! Tricky to get a yawn just so, let alone with a stretch too.
(I must look into who to try shortlisting, when circumstances permit - I'd like to find artists able to draw cybernetics and synths well)
@porsupah For synths and cybernetics, look up Strype on FA (fair warning: their gallery includes NSFW content).
I know of a few others, but can't remember names offhand.
@LadySil Oh, indeed! I've seen several fantastic examples of their work - that's the kind of overall look I'm hoping for. I've also seen one or two fully rendered synths that look highly appealing, though like yourself, the name(s) elude me.
Couple of days later and I'm still giddy over how this turned out.
