This journal post is up-to-date as of October 26, 2014.
I have pasted a link to this journal post in all previous versions so that anyone happening upon an old version can easily find the latest one in a mere two clicks.

I seem to have lost my oomph for making these.
Many props to MLP-VectorClub on DeviantArt for picking up the slack. Their work can be found here: http://mlp-vectorclub.deviantart.com/



VERY IMPORTANT NOTE:

*** PLEASE DO NOT REPOST THIS IMAGE!!! ***

I plan to leave the image up and available from this journal post for the forseeable future. Feel free to use my color keys as a guide when coloring your own artwork. But I'm tired of seeing people post it to DeviantArt without properly crediting me. PLEASE DO NOT DO THAT!

The exception to this is MLP-VectorClub, who have kindly and properly credited me. Thanks, guys!
