Self Initiated Brief - Sketchbook Work and Concepts

Following my research and experimenting into designing similar creations. Here are scans of the concepts I have created in my sketchbook.

I feel like I know have a solid idea of what I am aiming for when designing the bionic human. It will still have the humanoid body, so 4 limbs, torso and head. I hope that after these concepts that my final design will look appealing, but also practical and realistic, aswell as fulfil the ask of my brief.
