Right: Fluttershy from My Little Pony: Friendship is Magic (wearing her Element of Kindness around her neck)
Positions -
H: Left arm 60 degrees downward, right arm folded back so her hand is holding her E-Pichi microphone close to her mouth, eyes turned to the right

Five subjects in a V-formation, all in flight.

Notes:
Neopets (c) Viacom and Nickelodeon
Fluttershy (c) Hasbro, :iconfire-flye:
"The Neopets, in a way, belong to me as they come from my Neopets account under the username nightelf_37. Their names are, from left to right (skipping Fluttershy), Euryflavia, Tychophon, Aquanax, and Messerole. "
If all five will be drawn in roughly the same scale: "Actual Neopets are supposed to be less than half the size of an average pony (4 feet)."


"<insert title here>"
Lucy from Fairy Tail (holding the Spirit Key "Gate of the Lyre") expresses surprise and shock. Instead of summoning the Celestia Spirit Lyra, she gets the unicorn pony Lyra Heartstrings, who is enthusiastic upon seeing her and has a(n actual) lyre ready to play. Dialogue is optional if it can make the scene funnier.


"He Had It Coming"
Gray Mann of Team Fortress 2 is pinned to a wall by a very angry Fluttershy, who is dressed up as a RED Medic, and is holding up the Aputator to Gray's neck.
Description: "I believe we all know the reason why."


"Between the Raindrops" to furri-kira

For all: not attention-grabbing, simple
Note: I didn't want to put in more, since we all know what happened in "Suited For Success".


"I Won't Say I'm In Love"
Setting: Reminiscent of a scene in Disney's Hercules where the titular song was sung
TImerity (OC) lays on her back on the edge of a fountain, trying and failing to deny her feelings. A thought bubble coming from her depicts Rainbow Blitz (:devianttrotsworth:).
