Radioactive, large and green - it's the Incredible...

...Teenage Mutant Ninja Turtles. My wee boy asked me about these characters as he came across them on some cartoon channel so i did some doodles for him. No idea which character(s) i've drawn as i did a random drawing - so apologies if costumes etc are way off - cant say i've seen anything Turtle related for a long while, but good to try something different.
