Background Pony #FA2F
Looks pretty good. Human Firefly closely resembles Rainbow Dash with almost the same get up. I like pony Firefly with the two ponytails.
Firefly, the pony that inspired Rainbow Dash, I decided to make her both an Equestria Girl and a pegasus pony in the same picture. My favorite of the G1 ponies.
