Cool question, my (wo)man. First of, i'd argue the SIGN cover is still "super basic" but not in a good way this time around. I mean warmy colour is not enough, and the shapes are less wild than elseq, the contour stays the same in all beans, it's pretty strict in fact.
That said, worse ae covers to me: Tri Repetae, yeah. Anti, Anvil Vapre, Envane, Quadrange, L-event
I really don't appreciate that the new cover uses livesix design which was done way sharper on those posters (and if the album has nothing to do with live stuff it makes it even offensive)
