Shrapnel and bone

Here’s a pair of biomechanical sleeves I’ve been working on for the past few years , I’m sure this guy is over 6″6 so the arms are long,

The 1st sleeve was started 4 years ago
This has been the only sleeves of this style I have made .
I’ve enjoyed layering the black n grey to build up depth, it’s been a good study of technique for me and although I don’t make this style on people much , I’d happily tattoo this guy head to toe like this ,
