yes covers have to be in complimentary colors or minimal colors to work, especially ones like this.. sometimes real photo joints can work with a bunch of colors but they gotta be real smooth & all the same contrast lighting etc....
i'd say match all your colors up on this, switch the font to something nice & crispy and you got a decent cover, not a banger, but something useable..... as it is now it's not even useable in my opinion
