Which custom sheets should be taken down?

[Fighter The Echidna]

This sheet isnt very useful considering its only one pose

A simple edit of sonic's chao garden sprites. The spriter didnt even bother to change the shoes or eye shape of Sonic

Again, a simple edit of a sprite that was good until it was edited. He's the size of a regular character on this sheet

A poorly edited rouge sheet that only contains 2 animations
