First attempt at SNES Sparkster styled sprite

[Cobalt Blue]

It doesn't looks at all like something from a Sparkster game. For starters, your character is way bulkier than any official sprites (take a look at his arms and legs) and it still looks like a GBA Tails edit.
I suggest you to take a look at the ripped Sparkster game sprites found in the site's main page and study them so could applly the needed changes to your character: http://www.spriters-resource.com/snes/sp...index.html

And I haven't been?

judging from what you have done so far, no.
