aw, this is so cute! it must've been pretty complex to make her blink AND twitch like that xD
the only thing i'd suggest next time would be for the ear twitch to be more subtle, otherwise the ear will look like it's moving up and down. (see, like this twitch: www.google.com/search?q=mlp+ea...)
i like how you made some of the lines colored like that! (what i do is color the lines that have light hitting them a shade darker than the original color, and the ones that have shadow black. you might want to experiment with that, it emphasizes the lighting and gives it a softer feel.)
Awww so cute~ I really envy your animating skills. I can't animate to save my life.
Though, personally, I find it...well, kind of stupid to commission an avatar of an official character for only one person to use. I mean what if someone else wanted a Lyra avatar? They'd have to pay for another. I dunno, just my thoughts.
Haha, they could have commissioned it as a free avatar Would have made much more sense. But hey that's just my opinion, not going against the idea completely, just questioning. I'd love to see some avatars for free use, you make some really cute ones~
