Yeah, I've visited General Zoi's Pony Creator and to be honest, it's....okay....if you want to use it as a base or as a reference or if you don't have the resources to vector ponies, but personally I like to vector ponies from scratch using Illustator or Photoshop. One of the reasons being is because the colors from the vectors are more true and vivid. But before I vector ponies, I like to gather lots of references first so I know what I'm doing. Or, if I already know how I want it to look, then I don't need a reference. At least when I vector ponies, I can say "Hey, I made this in Illustrator (or Photoshop) and I feel proud to have made it using pure vectors." And it's something that I could actually upload to deviantart. Of course, I think you could upload something you made from the Pony Creator, but again, that's just playing around with a game and something you didn't make with pure vectors. I think vectoring ponies
is not hard, but it does take some time, dedication, and effort.
But overall, yeah, it's an alright tool. Also, read this: http://silvervectors.deviantart.com/art/Why-Not-to-Vector-from-the-Pony-Creator-351336918
Edit: I made this post when I was kinda an asshole and thought vectoring was better. I now recognize that a lot of people actually use the pony creator, especially when they don't have the time to vector ponies or pony avatars.
Hell, I even spent lots of hours just vectoring ponies. I know there are people out there that actually know how to use Photoshop, Flash, Illustrator, ect. and do artwork and they do it a lot faster, but maybe that's because they know how to use it and have lots of experience with it. I even had one girl on Skype try to teach me how to make a simple pony walkcycle. I am pretty sure it was 24 frames. And even that was hard, well not so hard because a lot of what I needed to do was already done. I just needed to use Keyframe Caddy and Onion Skinning to see what I was doing and see if everything matched up correctly and looped correctly. The hardest part was animating the tail. As I was doing it and playing back the animation every time, everything looked kind of crooked, so I had to keep correcting it AND I had to make sure that it looped correctly, so yeah that was hard. After doing all this, I would say at this point that animation is not for me, let alone puppet rigging. Just seems too time consuming.
