Another old practice coloring fan-art that I have, over Joe Madureira's drawing of the Teenage Mutant Ninja Turtles. You might be wondering why all of them are wearing red masks, this is due to the fact that in the early comic incarnations of this turtles. They do really wear red masks, that is before the creators gave them different colored masks. Teenage Mutant Ninja Turtles are created by Kevin Eastman and Peter Laird.
