I'm going to see if this image even shows, then edit explaining. For whatever reason I need 15 posts to show image urls which is rather frustrating.
Ok so I recently made some edits to my Smogon Sylveon (like over this weekend), the eyes have been hotly debated, they are not pure oval, and how this is will probably be the best (this is your project though do what you will, and not a complete copy of the smogon one)
At the end of the day I chose that the eyes needed to be distinct even if they didn't 'match' the other eevee's, Sylveons eyes are so distinct there is nothing we could use as a frame of reference.
-The mouth open isn't as readable, the smile is similar to Cinccino sprites in how it doesn't collide with bow/fluff and nose
-Putting black on the left of the bow kind of makes it not pop out more I feel
-I restored some of the outline, this may be personal preference though, do as you will.
-How anal are you about matching back to front? I know I am, it's a great back regardless
I probably won't pop in and do this much, Sylv is just near and dear to me.
