...I'm surprised. This is actually REALLY well done!
A bit of praise/critique:
-Sonic living in Station Square... Well, the guy's gotta have settled SOMEwhere, but his mom living there? Is SSquare in Mobius, or is this a comic reference I don't know about? :P
-Sonic's dad being a business guy; at first I thought that was a coverup for him being roboticized like in the comics so Blaze doesn't freak out/worry/feel sorry for Sonic or anything, but I guess it was funny to see that Sonic's dad runs around on work more than he himself does :P
-Shadow's voice is perfect. The actor and art works exceptionally well for him. MAJOR props there!
-Lol Manic being a "dude" who watches South Park/parodies. Nice touch.
-Sonia's voice kinda threw me off a bit, but I could deal. I mean, I just didn't see that voice "clicking" with Sonia, but that's just me.
-Sonic's attitude is picture perfect for who he is. In fact, everyone's personality is spot on for however they were portrayed. Congrats on that.
-More etc. stuff that I don't feel like typing. :P
All in all, this was a very good concept and storyboard, and actually feels like something you'd see if Archie Comics, the makers of the old Sonic TV series, the Colors writers, and some new talent banded together to make a Christmas day for Sonic that didn't involve ass kicking. I loved it
I'd very much enjoy having permission to do an animation of this, if I could have your permission :D (would take a long time if I ever do so, but hey, it's fun to draw :P)
