A Very interesting pile of images has released dedicated to Make Your Mark. In slideshow style format, it goes over a bunch of things for each of the mane 5, from their personality types, to full on bios and color guides for their 2D forms. Along with that, it has a bunch of neat flat background assets, probably for toy boces and other thinkgs.
