Jackson Sze is Senior Illustrator at Marvel Studios and occasionally posts art from his movie work on his Instagram account. Last month he uploaded a gorgeous piece of keyframe concept art for "Ant-Man," and now he's followed that up with another piece of Ant-Man-centric concept art, this time from this year's "Captain America: Civil War" -- specifically the memorable hero vs. hero airport battle.

Sze describes the piece as "an illustration of #antman about to wreck #ironman from the inside out," and you really wouldn't want to be in Tony Stark's shoes when having to face an enemy within, Scott Lang-style.

Of course, the concept art we are all most eager to see is from future Marvel movies –- is there a chance that Sze might post something from, say, the upcoming "Ant-Man and the Wasp" movie? It seems incredibly unlikely he'd get permission to do so from the higher-ups at Marvel Studios, given the infamously secretive nature of the franchise, but the peeks behind the curtain at previous Marvel Studios films remain compelling.

Paul Rudd’s Ant-Man will return in "Ant-Man and the Wasp," scheduled for release on July 6, 2018.
