I should describe it better:
biomechanical in tattoo terms means a reimagining of machinery in a biological setting- which i think is lame.
but I mean like a cut through the skin- so more towards anatomy.
imagine an MRI image on the exact location of the vertebrae and the acromioclavicular joint and all the ligaments there in.
Like a Da Vinci, but on the skin:
thats the true meaning of biomechanical. the mechanics of the living things, in this case the arm.
Just dont get too caried away
