Each week we search for the coolest comic book art that you won't actually see in comics. The reason you won't is because artists often draw sketches for fun or commissions and post them on their sites, blogs, and Tumblrs. Some artists even arrange commissions through their sites so be sure to check them out for more information.
Robert Atkins posted a bunch of new sketches on his blog. The Superman/Batman one was drawn with his brother, Brian. The last couple shows his art from a jam piece. Robert did Loki, Clayton Henry did Winter Soldier, and Craig Rousseau did Kang.
That's it for this week.
