Sorry dude...IMO, your co-worker sent you a photo-shopped image. zoom in and look at the pixalization around the wolf's outline (really noticeable by it's rear paws)...also, zoom in on the dudes left hand and arm...all wrong...unless his left arm in 1 foot longer than his right and has a plastic hand. Guys left leg is also outta whack with the basics of human physiology and center of gravity. Angles are all wrong...impossible to hold something that heavy comparing upper and lower body postures.
Plus...and I guess the obvious one, the rear legs, front legs and head of the wolf should be all be "floppy" and hanging vertical if it was dead..not in the trotting position...rotate the photo 90 deg counterclockwise and you will see what I mean.
A solid C+ for whomever made the photo though...decent enough effort.
cheers
