Content-wise any stuff I commission never goes beyond PG.
The idea for the pic is based on "Rarity Investigates" where Rarity is watching Rainbow Dash perform with the Wonderbolts from the bleachers in Canterlot. It would be like that except she's not a reserve any more. Kydose would be snuggling up to Rarity while she's watching.
My own OC (that's this grey pony here:derpibooru.org/500607?scope=sc…
) would be sitting in a different row. Like you do with Kydose and Rarity I'm doing my best to put him in a believable relationship with Rainbow Dash; although at the moment they're only friends.
Art-wise, I don't have too much of an idea right now who I would commission it frrom
