FrostIron Fanart inspired by STARSdidathing’s “A Deal with the Prince” on AO3 (http://archiveofourown.org/works/11422461/chapters/25591161).
According to the fanfic, Tony is an Asgardian weaponsmith. Here, he is wearing a leather apron and glove, chewing on a tattered quill while looking at some blueprints and adjusting the calculations in his head. The beads of sweat is because of the amount of heat in the workshop. The protective goggles are loosely inspired by steampunk style and is pushed up into his hair, giving a messy look.
Smittened chibi Loki is making grabby hands at the precious AKA Tony. He wants the precious so much!
