This really was a fun theme for a challenge and I love all you got to do with it - love the coloring (power trio! gadfly!), love the lighting (3 is such a good icon, and so is glowing eyes), love the grungy effect the textures give to this set. Your blocking is also great! I like how you used it to portray the tropes, like in 3, 5 and 6.
Wonderful job :'D
