The cutie mark is one of the most defining elements of a personal OC's design, right next to species. I had a cutie mark way back in 2013 when I first designed Dusk, but as I returned to the community, I realized it no longer fit, and perhaps I had designed it too quickly back then. Cutie marks are all about destiny or special talent. I've spent weeks redesigning this new one, and I think I'm about ready for the reveal.
