Started sketching with no real goal while watching Ghost In The Shell and got carried away.
I'm not super adept at rendering realistic mechanical devices but I'd like to think I get the gist of things down okay.
To The left a cyborg under maintenance. To the right a Cowbot packing some head. And up above, a creepy braincase observation model cyborg. Having long since lost all of its original body. Still it serves its intended functions.
