Wow! Very very VERY good! Way better than any of my art :P. I'm gunna start drawn' more sonic chars.... or... start drawing sonic characters period! Yours are the best I've seen so far though!

I really love the picture! To be honest I like Shadow better.^-^'.I have a soft spot for him!!!

Oh, I love this picture. Very nice use of color and shading to get the shiny Super Form effect. (On that note, kudos for konwing it's Super Shadow and not Hyper. That's the weirdest debate ever, it is. 0_o) Oh, and I LOVE Mobius. Those clouds are awesome. I have one minor, itsy-bitsy nitpick - both hedgehog's eyes, when they go Super, are red. Great piece overall, keep drawing!
