it was a week-long school project where I needed to use tracing paper to draw the muscles over the skeleton. I agree its unbecoming. I can certainly transfer it to something more appropriate at some point.
what crazy said, and I'd like to add that I was looking at an armadillo during this project and I found no other bone-structures in it's shell besides the skeleton itself. thus I figured fat, muscle, and water would fill this area for the krogan.
