Octopus chest tattoo -in progress

octopus chest tattoo, black and grey in progress picture i took yesterday after the first offical heavy shadeing session, we did some super soft shadeing on the lineing session  as background to build up on, as you can see the red, new, irritated areas, and the background shade showing its true grey values.
this kids a champo, so far we have like 6 -7 hours in this thing, and this is his first tattoo, LIKE A BOSS.
hes already contemplateing possibly a custom biomech peice halfsleeve tattoo on his arm to compliment his chest peice, because the octopus goes on the front of his shoulders so much...
except he wants the literal term of biomechanical, which to me is skin rip/ gears and overplayed stuff, i opened his eyes to what don mcdonald/ guy a/ hr giger do, hopefully he bites..
thinking... bone spurrs with anchored metallic peices with gauges and stuff... maybe a human growth cyborg war shoulder xD
idk, brainstorming
