I can see your enthusiasm in how you play your characters, and that's a really great thing! I have greatly appreciated how you've taken the time to welcome me and interact with me over plurk.

As far as your playing is fine, but I sometimes feel a bit disconnected to Tails. I've given this matter some thought and the biggest reason that came to mind was the variety and difference of his icons. The range of emotional expressions he has is very similar -- I think in part because they draw from the same resource? For me, this creates a bit of sameness as talks from response to response with mostly the same pose and small differences in eye openness and mouth position. They're like "Tails emoticons." Language, as I am sure you are aware, is conveyed with the body as well as their words.

Coco, by contrast, has a lot more variety of mannerisms and positions. Compare this icon with most of Tails' -- she speaks more of how she is feeling in how she expresses herself. I think that were you to revamp your icons with more expressive ones, even if they weren't ponies, I think you'd see a noticeable difference in how he portrays and carries himself.
