Bender Avengers Sketch

Because I finally admitted to myself I'd probably never get around to this... here are the sketches. xD I'm so unmotivated to finish it. Also, Bo Lin isn't in here because I made him the hulk, and if I inserted the sketch it would be WAY too crowded...
But please tell me what you think!

Iron man ~ Lin Bei-fong
Thor ~ Tenzin
Captain America ~ Korra
Hawkeye ~ Mako
The Black Widow ~ Asami
The Hulk ~ Bo Lin (not shown here)
