Wow very nice, a very good view of tails, a different perspective for sure, but also an acurate way to show him saving Sonic as usual. The color and black inner rounded border was nie as I don't see that too often. Sonic looks irritated with having to be rescued but he is prolly either used to it by now or just enjoying the ride haha. Also having the enemies trailing along was a nice touch, just a few ideas to show more..maybe add more rings and maybe them a bit more circular, also the enemies have some odd contrast going on in a like almost fog over them, maybe change the contrast to darken that in a bit more, the enemies also seem a bit smooched but the rest was great and a great view of the characters swapping you have here, hope to see more from you soon.
~~THINGS TO IMPROVE ON~~
Well as suggested more rings and better circular definition on those rings
