It crossed my mind and I somewhat tried to find the five rings but its very difficult to find all five of them in that position and still make it look HQ.
And I wouldn't want to repeat the same one over, i think it would look too funny.
yeah i like the purple. id suggest some more small accents of color in different places but the background isnt really detailed enough to just add color to some parts or anything. it would look cool though, i think.
