Skins SKIN HAS NO REFLECTIONS

[SANTTIFRADA]

Hi sorry for bothering, I am new to making skins and i have a problem with the reflection of some colors, some colors are glossy and others are matte, I am trying to get the all colors to reflect, it would be of great help if someone knows a solution. I tried everything for hours and this is my last resort I will leave an image as an example. Thank you very much
