Tails is a guy just pointing it out hehehe its mention in comics and games and even shows sonic thinks of him as a little bro and tails falls for cosmo in sonic x. but whatever its your art work i shouldnt tell you what not to draw
Why is everyone sexually confused about Tails, I get that genderbending favorite characters is kinda fun, but it seems that a lot of people go a littler too far with it. Like the people who get tattoos of the simpsons and star treck, and get married as thier favorite characters. No offence intended, your picture is fine, I am just asking seeing as how you seem to be like the first kind, and have not gone to far, and are thus much more reasonable to ask of opinion.
I personally think that the female version of Tails is better. Especially a certain version of *her* that I've seen. Plus if you didn't know the character and heard the girl like voice that they always give him in the games or episodes, you'd think he was a female to begin with.
I had always assumed he was a male. By name/looks alone anyhow. I don't have the original game box, so I can't remember if it said he was a boy or not.
But he does get girly in later games, but that's only because how the artist/game designer of those games saw him (like an annoying kid brother type of thing with a underdeveloped voice). I'm sure the one that originally created Tails thinks *What the flying f**k?!?* when he sees gender bends and all the other stuff out here xD
