These are amazing Nitro! There's something wrong with Sonic's running though.His upper body looks like he's running, but the way his legs are moving kinda make it look like he's only walking. make the legs go alittle higher so it looks like all of him is running. Also, I don't even think you should let silver go full speed. if you're making this Sonic The Hedgehog 2006 style, since he could only kinda jog and not go as fast, I think you shouldn't make him go full speed. You could make him shoot a box or something.One more thing, make his eyes look alittle shorter when he's running so it looks like his head is slightly tilted downward.
