Here comes my opinion.
yes those back grounds look awesome but the coco fiber eventually starts falling off and looking nasty.
It may have been a little too wet. How long did you let the silicone sit before you put the cocofiber on? Even a few minutes and it will start to form a dried layer and wont let the fiber stick to it.
If you use brown or black silicone the places that did not take wont show through as bad
