hi.
i'm really not sure why people aren't already giving you cnc, this is a commendable amount of effort you've mustered and i respect that. i'll try my best to help you out here.
orange/black: overall look of the head is boring, it seriously lacks flow. you have interesting shapes going on for the head texture but you seem to enjoy separating them into pieces? things just don't link up and i find it bothersome, it just killed it for me.
blue: idk what kind of pattern you're going with here but they very much resemble tyre patterns which doesn't seem to make any sense since they come out of no where? i suggest you scrap it and try something else.
red: it looks interesting but what exactly is its purpose? i feel like you're adding excessive amount of elements which don't unite with one another. they're basically random pieces of nothing being forced to become something.
to conclude, i'm going to guess that you start off on a blank canvas and draw random things to make it a "head texture". you have this generic idea of a robot but you have no idea what you're working towards at all. i see a combination of a pig and a robot with face paint and tyres for ears behind a sheet of metal that covers the entire face. what you need a solid idea before commencing work. i'm not saying it's wrong to start without one but at least have reference pictures - it provides you with guidelines towards what you want to achieve. i would give you a more in-depth cnc but that'll all be useless unless you work on your foundation.
you're showing improvement and i really like that. march on dude.
