A rare instance where I straight up just referenced an existing image for an emote, in this case the 5th panel of page 5 of Burning Wheel (the Gigamix adaptation of Battle & Chase). The panel was perfect for what I wanted, and I really like Roll's racing jumpsuit, so I figured "why not?" And since this is specifically a Battle & Chase emote, I decided to use the palette from that game instead of the Rockman & Forte palette like I normally would for Classic MM emotes.
Her hand was tricky to get right, but I think I managed to pull it off well enough (it helps that I had a pre-existing image to base the positioning off, though).
