Trouble trio
So I've had this in my head for a while, finally got down to drawing it! I've already introduced these three before, but, from left to right, these are UltraViolet (UV), Midnight (Night), and Brite! My three mischievous youngsters! These three are best friends, and get into all kinds of nonsense adventures (although Night is usually being dragged into them).

UV is the oldest, so he's taller and a little lankier. He's also the biggest troublemaker. He routinely dares Night and Brite to go into scary places or do stupid stunts, but when Brite calls him out, he's usually too chicken to try them himself. He's a lot of talk, and very rambunctious.
Night is the second oldest, but he's the shortest and stubbiest of the trio. He's also the biggest scaredy colt. He's a very gentle soul, and doesn't so well under pressure, plus he tends to be afraid of his own shadow. But UV and Brite both help him to come out of his shell, in their own ways.
Brite is their fearless leader, despite being the youngest of the three. She's always finding new adventures to follow or stories to reenact, and she keeps UV from picking on Night too much. She's a big believer in justice and fair play, and she only teases UV when he deserves it.

I might add their dialogue here later, but it'll take a bit for me to jot down.
I tried a background here that was somewhat in the style of the ones in MLP;FiM, but it's pretty haphazard and sloppy. Still, better than just another blank background, right??

UV, Night, and Brite all belong to me~
