I'm working on a big painting that will feature portraits of all the avengers from the film (as well as the villain). It will be fun once I get all of these sketches done! I've got 1 more avenger ( Bruce Banner) and the villain (Loki - in progress) to go before I can compile them all into one large composition for my painting.
Here are some early rough sketches of the portraits I've finished so far in a collage. :)
