Very cool! I don't know what that filament stuff is on the back left, but it's very nice.
Would it do better to have the base more clearly seated on a surface? It's almost floating, but I do see some dispersed reflection there. Maybe the table surface should have a different set of properties. I dunno. And I'd be curious to see the frame rendered with higher contrast so that the background isn't as light.
The wee mechanical beastie is the obvious star of the show. The proboscis could probably be even pointier and needle-like, if you wanted to give it a go. But it's really just so cool, even as it is!
