Yes, a lot of people have vectored this pose of her over the years. Personally I always wanted to fix a couple of things there.
First, the back legs used to look weird in my opinion, so I changed them a bit.
Second, that cello (or whatever it’s supposed to be). Sure it looked ok back in 2011, but when I saw that show used the same freaking vector of it in episode 100, I was like “man, and I thought I was lazy!”
So, to cut long story short, I decided to make a better-looking one myself.
And then the dress. Since people really loved the one I made for Applejack, I decided to make one for Octavia as well! Enjoy =P
