Well all the characters from Free are basically represented with animals and actually the guy with the purple hair (Rin is his name) well you guessed it, he's a shark, and you can see on almost see everyone's shirts there is an animal on it, like there's a dolphin and whale, penguin, butterfly and shark...... so yahhh
Love their expressions and the line work here! It took me a while to notice the guy at the bottom, though. I think it might be the color palette on him- he blended into the couch a little bit. This is still a gorgeous drawing, btw! I figured I'd mention that since this is going to be a print and all. Hope you don't mind.
