These sprites are old. They were before I had the idea to come up with my username here.
Anyways, yeah. Kirby spriteys affair.
I think I messed up the feet in the Dark palette (supposed to be some darker red) and i think Kirby looks a lil like a square when he's got a thing in his mouth.
Still my first time putting sprites here so yeah I'm a lil bit nervous.
You may want to get rid of the blank space message before submitting it to the main site though. As for the squareness, you can make it look a bit more round by adding another column of pixels on the sides and maybe rows on the top and bottom. Right now the change in the number of pixels (1, to 2, to full length) is too sudden of a change, so the angle is sharper. If you have a more gradual change (1, 2, 4, shorter length) it'll smooth out a bit.
Really solid work overall though! I'm excited to see your sheet on the main site!
Oh! One last thing. You might know this already, but if this is your first submission it may take a little while for it to be accepted. The admins have a major backlog and they need to vet new submitters. So don't get discouraged if it takes a while for your submission to go through.
