You can find the reverse side of his design here.

I had fun drawing this one, I think the pose and anatomy turned out great. He's got a medium-ish coat, with a very thick, spiky-furred tail after which he is named.

I based his new colors very heavily off of his mother Rosepetal's updated sheet, since they're both dark cream tabbies. Sparktail only has striping on his face and tail, it didn't look like him when I tried to add it to more of the pelt. The white above his one eye has been removed, but otherwise his pattern is largely the same as his old one.
