I had a really great time coloring this.
The original is by
and can be seen here
I took a few very small liberties in the design. Like I turned Rarity's shoes into high heels, I gave Twi shoes too, eliminated the scroll from near Twi's head, and I'm pretty sure Rarity is supposed to be wearing stockings, but I turned it into a garter instead. I see Rarity as wearing white stockings, and seeing as this is an anthro version and she's already white, they wouldn't have been seen anyway. In retrospect I could have put her in black stockings, but I've always viewed white stockings as classy and black as slutty, so... garter it is.
I really, really like these designs of the characters. Rarity's dress came out just divine, and I adore Twi's round little arms. The lineart for this was absolutely splendid. Give the artist props. I literally couldn't have done it without the original artist.
Bonus points if you can tell what book Twilight is reading.
