Original Description:
 
(Princess Twilight Sparkle had asked Solis Flare if she could meet up at the Castle. When she entered the Throne Room, Twilight stood there with her friends.)
 
Princess Twilight Sparkle: Solis! It’s so good to see you!
 
Solis Flare: Hi, Princess Twilight! Why did you ask me to come?
 
Princess Twilight Sparkle: Well, it appears that there’s some issues me and the girls have to take care of.
 
Solis Flare: Oh. Alright!
 
Princess Twilight Sparkle: I’ll have to take Rainbow Dash, Pinkie Pie, Rarity and Applejack with me. Fluttershy will be staying here with you, since she has injured her wing.
 
Solis Flare: But.. what will I be doing?
 
Princess Twilight Sparkle: You’ll have to take care of this while I’m gone, (She handed her the amulet.) It has the ability of raising and lowering the sun and moon.
 
Solis Flare: ..You want me to be in charge of that?
 
Princess Twilight Sparkle: You’re the perfect pony for the job.
 
Solis Flare: What if I mess up..?
 
Princess Twilight Sparkle: Fluttershy’ll be here to guide you!
 
(Fluttershy looked over at Solis, smiling.)
 
Solis Flare: Alright, Princess!
 
Princess Twilight Sparkle: Are you up for the task?
 
Solis Flare: You can count on me!

I tried shading this one! :D I also removed the extra ear and eye details I usually have, to make it more show-friendly.
