Concept art revealed for Avengers: Age of Ultron's Quicksilver, Scarlet Witch, and Tony Stark's Hulkbuster!

Last night Marvel Studios: Assembling A Universe aired on ABC and it blew me away. To watch the Marvel Cinematic Universe be formed from start to present and watch how everything worked to weave the stories together was incredible. During the special they showed some fantastic concept art for Joss Whedon's Avengers: Age of Ultron. The concept art were for designs for Aaron Taylor-Johnson's Quicksilver, Elizabeth Olsen's Scarlet Witch, a Hulk vs Hulkbuster (Tony Stark) fight, and a battle scene in which the Hulk and Black Widow stand back to back during the thick of it all. During a behind the scenes clip from the film you also get to see a real shot of the Hulkbuster armor's fist and forearm which looks amazing. You can see that in the video at the 1:10 minute mark.

These images are definitely exciting to see and I am really liking them. I'll also add that the Avengers' Quicksilver looks immensely better than the Quicksilver that we'll see in X-Men: Days of Future Past.
