I’m sorry that I write back late.
I didn’t thought someone would still reply. 
@BackedUp20; Yes I’ve resolved it. It doesn’t look great but its ok, I can’t do it better at the moment. Need to go on ^^
@JamesEmory; No it wasn’t planned to make a mobile game. I tought it would be easier to do it this way than modeling the hoops out, also I wanted to learn using Layered Materials
And don’t forget that I have no idea what I’m doing g
@unit23; спасибо! Good ressource. Maybe it will look better with a Displacement Map.
