i tried a couple out of curiosity:
>>6530932this one looks really nice with the very slight scratched look, it blends super fine with the symbols on the homescreen and looks like the pic kind of belongs to the phone. it actually feels kind of "warm". might just wanna change the brightness to a slightly lower value.
>>6531180like the style of the motive, makes the phone feel "lighter" because of the blue.
don't like it as much because there is too much "change" of color value, from blue to black in just one pixel; so it feels like there's too much going on on the screen. same goes for
>>6531182 and
>>6531291
