This is 'Goodbye, my brothers', a series of super sad Ninja Turtle fan art by Joao Pires. And not super sad like they look like they were drawn by a preschooler, super sad like, crying sad. Each depicts one of the turtles mourning the loss of his brothers. Which, personally, I don't even want to think about. But if one had to go I definitely wouldn't miss Donatello as much as the others.
Hit the jump for the other three.
Thanks to T.J. O, who doesn't always weep, but when he does he weeps manly tears exclusively.
