I think the eyes are fine already, but did some comparing to the original sprite for fun.. it seems the current HD eyes are the correct height already.. until seen here
Now we're talking, that's the first one I've actually liked... but he looks to much like a robot now(cut of his head, make his eyes blurry and you have a dead Tails).
Thanks alot for those images guys! Keem 'em coming! Tails belly and parts of his body fixes will be included without a doubt, about his eyes I've Started doing some quick experiments boys. (As stated before, cannot dedicate it much time now due pending work on Sonic's frameset) P.s. For every-Illustrator users, here is the .AI source if you want to play with it.
I actually just edited the .ai file, so it's already in vector format. But yeah, if you guys don't like the shape of the highlight I can change it a bit. I made it kinda curved to make it appear that his eyes aren't flat. I actually don't really like his left eye, it just looks a bit funky for some reason. I think I'll mess with that a bit real quick.
Shit. That's the first S2HD Tails that doesn't feel wrong in some way to me. I think we're finally getting there =P
This is a rough edit in paint but this is what im on about it needs shifting over. But other than that it's perfect.
