I've made some custom sprites of the Mite enemy from the Subspace Emissary.
Here
is the sheet
Here
is the icon
Couldn't really make it fit into any style beause of it's small size. I hope it get's accepted.
Meh, it's okay for a small sheet of a small enemy... Besides, they're supposed to sorta mimic Mr. Game-and-Watch, right? But smoother animations. Which means you need a few more frames... Especially for the idle poses. They do strange stuff like stretching our their arms, etc.
Also your credit tag is bigger than the entire sheet. Shrink it down some.
I've improved the sheet. I'vetest animated the walking sprites and found errors so I improved them. I also added the 2nd idle pose. I think there's only two idle poses for Mite.
Here
it is.
