Based off my older picture with the same title: [link]
I mainly did this because I wasn't really happy with how they came out in the last picture, so in this one made some improvements to the characters.
For Sonic: I felt that he just wouldn't just be sitting teary eyed at what happened, I think he'd still be smug and all like "Come on Egghead, do you really think this will stop me?"
For Tails: While in the last picture I can see him crying at the situation, in this version I wanted him to be upset and kinda confused at what just happened.
For Knuckles: I can see him being all angry like in the last picture, but I can see him being all pouty as well, so went with that. (Still kinda not to happy with how Knux came out, but out of 7 sketches this one came out the best.)
As for their ages: Knuckles is 4 years old, Sonic is 3 years old and Tails is just 1 year old.
Why the lack of Eggman in this picture: I wanted to put him in this but based on how the characters are looking in this picture, I feel that they're looking at him off screen, plus he just wasn't coming out right and didn't want to put a side panel just to show him.
Anyway hope you enjoy. ^^
