A silvaze Story: Consept characters

So as you know, I've changed the style of the comic quite dramatically when I switched to drawing in my book. So here some of the character designs.
Note: They're 10 years older from their current age.
I made knuckles design a mix of his old and sonic boom design. He is very tall and had a large torso, but doesn't have large muscles.

Oh yer, Zeena from sonic lost world is in it too, This is something about the story line I added, You'll like it...well maybe.
