I didn't know the technical definition of "biomech" but I can deconstruct a word with the best of 'em, and bio (life) + mech (mechanical) caused me to expect something in the manner of a Borg character like Hugh (Three of Five), or the Bionic Woman, or the Terminator where you can see flesh fused with mechanical engineering. Not that which Dani did with her tattoo...it had me wondering, Is biomech a representation of anatomy from the inside out? Her skills were solid but the image was nonsensical.
I thought Laura's design looked way stronger on paper, those disks stood out more boldly in the background, than her actual execution of the tat on the canvas.
I agree that Jason's was the most legible/readable of the three.
My main complaint--mind you, I watched IM perhaps in seasons 2 and 3, not sure--Tatu Baby was in one of them and WTF did Dave bang her or not? excuse me--and then just happened to find a hole in my TV lineup that IM filled with this season. And after 13 seasons, they STILL give this hasty, rushed don't-look-too-close-now presentation of the season finale tats.
