Good one on the tie! It shouldn't reach all the way down however and peek at the bottom (sorry, I'm strict with this). Many kudos for going with a vest and no jacket, that's just the right thing to do.
I have an all-black outfit with a green tie, wanna team up? xD (j/k)
I plan on doing it again. I want to make the cutie mark a little darker, find a better crown, have some fancy cufflinks, and have ears and a horn. (Sadly I didn't have enough time to make the horn and ears....)
Wow man! I love this! I have always loved genderbends, and I've never seen a Celestia's genderbend like this one. I've only seen the Lord Solaris version and I didn't like it. But this... it's amazing! Great cosplay!
