EDIT - Dec 08, 2013 - This is OLD, like really, really OOOOOOLLLLD and outdated, and there are better methods out there. I don't even do vectors this way anymore. That said, it's still useful as a guide on how to use the pen tool to make shapes specifically for pony vectors in a manner where they're layered efficiently easily modifiable. Just felt the need to point this out as I am still getting messages from people who don't understand that this is old and that I know there are alternative methods. I thank you all for your input.
Before I say anything, if you're familiar with proper vectoring at all then once you've heard what I do you'll realize I'm not making "true" vectors with the process I use. This might seem a bit odd because what I do means that if I wanted to make a larger version of the image I would basically have to scale the paths I've made and re-"paint" the whole image, but I'm just doing these for fun so I make them large to begin with; the end re
