Assistance with Custom Spriting

Please don't use attachments. They're against the rules.

Anyway, your issue is that your sprites have jaggies.
Look at your lines. See how they make... steps? You've got corner parts on your outlines and you need to remove those.


I did that on the head on the white one.

See how the outlines are a lot cleaner now? They aren't perfect and still have issues but they aren't so ugly looking. Go through your sprites and clean them up.
