Love your expressions on Sombra. The before-coffee face is sort of my favorite. XD
There is a pretty good fic www.fimfiction.net/story/19545… about his return on fimfiction. It's marked as a Twilight/Sombra paring but so far I like how Sombra is portayed here. In the 4th chapter, Sombra is being transported to Twilight's castle (to be reformed) and even hoof-cuffed and without his magic, he freaks out one of his guards and Rainbow Dash stares him down but when he slowly grins at her, she even looks the other way. I could so see your artwork portraying this scene.
Yeah, its one of the most enjoyable fics right now. The part where Spike glances at the clock and finds Sombra staring inches away from his face and causing him a chair fail, really made me LOL'd. Sombra's so eerily quiet. King of Shadows
