Not Bad.
As a member of Sonic Paradox, I can definitely say that this could make it into the next Volume. Just work on your art a bit, and go join the Sonic Paradox site. Also, I know it goes against your flash, but the whole motif of the Tails Doll is to be scary. So, I think it'd be cool if your flash started out "Can you feel the sunshine?", have the Tails Doll's eyes pop up, and then say "Does it brighten up your day?" And then have the Tails Doll appear with an evil grin.
