The races represented here are as follows:
Pony = Mage
Reformed Changling = Light Elf
Hippogryph = Aasimar
Dragon = Dragon
Yak = Orc
Griffin = Harpy
By the way, I anticipate a few people bringing this up, but the reason why I kept dragons as they are only making them quadrupedal was for two reasons: way back when I started drawing My Little Mages, I made Spike more animalistic, so I am keeping things consistent here. The second reason is that it is sort of a funny role reversal since dragons in the show are one of the very few bipedal creatures shown.
