Which should I draw first?

Okay, I had played with my phone for a while(no, not games. just checking on random files, etc) and then I found these doodles lying around in an unnamed folder.

The first one is an old, like REALLY old, character named Candy Cane. I actually made her probably on the year which Wreck it Ralph was made. She was a candy bunny based on the Sugar Rush theme.

Second one is the one I made recently. Remember Shadow Silhouette? If so, you could have read her bio. I have mentioned a mare bearing the name of Colorful Tears. Well, here's her concept design(at least, the first concept design. I'm not done with her yet).

Last, but not least, the Mistress. Yeah, very original. (insert high levels of sarcasm here)

She's part of an upcoming project, but I'm not launching it until next year, or next, next, year.

Other than that, tell me down in the comments below who I should draw first. The character I made probably five years ago? The character I made recently? Or the character in use for the future?
