the quality is about what is to be expected with a 2k AO. To make the quality better do your skin in a 4k AO and make sure the stickers are individually upscaled to 4k before importing them to your skin. then once the skin is done you can "resize" the entire skin to 2k or 3k that way you keep some quality at lower resolutions. Also it can be tricky to get decent quality on a carbon surface there are ways around this. if you need to know more DM me
