Nachi "SH-166" (Critique required)

SenChi

Good day, everyone !

Recently I have finished another artwork of industrial robot "Nachi SH166".
If you don't mind I'd like to ask you, folks, for some feedback and critique.

What do you think can be done better? Where I can improve?
So I can use these hints in my next work.

Thanks!

This is really cool.. I think what stands out most to me is the too even and random grunge. Imo it should be a lot less and more in form of dust collecting in the corners
