Cosmo's mother takes Dark Oak's hand and they vanish together. 4kids had Cosmo talk to Sonic from Heaven through a tree at the end. In the original Japanese, it was Dark Oak talking to Sonic from the tree.
Nice job! Is Tails ready for fatherhood? Cream might be able to help if she can resist the temptation to turn her rival's child into a flower crown...
However, since I'm so perfectionist, I feel the need to point out some mistakes: 1) The sign in Tails' house read "Home Sweat Home" (it should be "sweet," not "sweat"), and 2) The characters have three fingers and one thumb (like the Simpsons) instead of four fingers and one thumb (like humans). Besides these, you did very well. Keep up the good work.
The hands are indeed humanlike, but my observation was that the number of fingers was incorrect. Also, was your comment about "the correction of [my] perfectionism" meant to imply that there's anything wrong with being a perfectionist?
No i mean, if you search Sonic or Mario or anything related to them, they are given 4 fingers and 1 thumb. The only time Sonic had 3 fingers, one thumb was in the first few games and the original Sonic the hedgehog TV show. But now-a-days, it's 4 fingers and one thumb.
In the scene containing Cosmo, Tails, and Sonic, Tails holds the button in a three-fingered hand, as does Sonic with the seed. However, at the same time, Cosmo is shown with open hands that each have the correct amount of fingers (four plus one thumb).
Meh, I'm not being consistent with the finger-count, and if you go through my other drawings, I'm sure you'll find many characters having five fingers in one pannel and four in the next, or two left thumbs, and stuff like that.
I'm a perfectionist myself, but perfectionism can only go so far.
