Please critique / review my WIP (Work In Progress)

Hello World!
I seek your valuable 2 cents on my Work in progress bust.

Thank you all in advance!

few pointers:

  1. Primarily seeking reviews . critique in terms shapes and forms Proportions and Hard - surface elements.

  2. Not specifically looking feedback on colors textures or renders (I colored it to help myself get an idea what shapes work and what don’t - not sure if this is the right approach)

  3. Although i am almost sure about all the Hard Surface elements (their placements that is) - i will do one more pass after i gather some reviews and work on those. and then work on the “Scars bruises” on skin for the mechanical implants
