Drapery/Cloth Folds improvment help

Rex109

Hi guys! I'm new to the forum so forgive me if i'm posting in the wrong section. I need some help to do Drapery/Cloth Folds on my armchair and my couch. I'm trying to make a photorealistic project but those folds are very very odd and bad. I Made a low-poly and an hi-poly version and i baked them with Substance Painter 2018. Can someone help me with an online tutorial/article? I really need to make a low poly version of it. Thanks in advance.

Here are some previews rendered with Marmoset



Here is a close up of the folds
