Sonic Short 4 Redo 2

Sonic Short 4 for TheWax's collab.

Added details and mouth fbf. (pause the vid when Sonic opens the window and zoom in to look at the books' titles and a familiar character)

Please comment so that I may make this better.

I'll update this once more when Gamebuddy sends in Knuckle's lines.

::Edit::
Gradients are darker to look more shaded ^.^

::Edit 2::
Knux has ghost trails on his arm movements and he points to himself.
