oops. PJ does not allow semi trans pixels because we can see why you did it here but allowing it then opens others to use trans causing chaos. Use the 'edit it' under the art to upload a revision and remember to hit the submit button again.
yeah, I made the part around it transparent on purpose so that it would look better in backgrounds.
Looks pretty clean, but all colours except the black one are transparent.
okay, I'll have to do it later when I have a chance to fix it.
