Some frustrations with my shaky inking led me to experiment with sketchier lineart, and also try for a slightly more painterly look than I normally colour with (turns out SAI's marker tool is easier to use if you pen-shade with another colour first).
All three of post-Heroes Espio's English-language voice actors have portrayed him with what TV Tropes would refer to as a "badass baritone", but--and I'd genuinely forgotten this until I'd read up on Team Chaotix again--he's only 16. Quite a bit of disconnect there (seriously, go look up the cutscene in Generations where you de-statue him. I don't remember any 16-year-old classmates of mine sounding like THAT).
Which led to the mental image of Sybil (a librarian in her early-to-mid-20s) dating him for a bit, only to discover that Espio is, in fact, jailbait. Whoops.
To be honest, I have met many guys in my classes when I was in high school who had some pretty deep voices. I guess it just varies depending on the person.
I wonder who is that girl with the glasses? What's her name?
Glasses-girl would be Sybil, one of my characters.
