Apparently, I'm only allowed to write reviews on this particular piece; however, the runner's anatomy was taken from a video of a race (the anatomy of the reference in question appeared strange as well). I can understand what you mean by "popped out of his body", but I was honestly just referencing someone who looked as if that was happening to them (perhaps it was my mistake in referencing runners with bad form).
I want to do a background to this, but I'm afraid it would be too tedious.
