My only critique is that, if I remember correctly. Shadow's rings are flat on the inside, where they press up against his wrists and ankles. But that's a minor detail that's hard to draw by hand, and I don't think anyone will care about it.

Seeing this reminds me of the old artwork I'd see of Sonic back during his earliest game days, whatever the artwork was, it always involved the Hedgehog hero and several rings floating here and there. Having Shadow is a great change. Good work and thank you for the fond memories with this pic.
