Unsure how to separate the layers for this jacket!

[drowsy notch]

Sorry for the incredibly messy sketch (I was in a rush) this jacket has completely bamboozled me in how the layers should be cut, I have a small general idea from my experience of model making but want to really make it pop!

id say something like this overall

you could also separate the texture from the base

chains also separated, and id also separate the zipper metal dangly thing as well

you could also have the blue and cyan part as one thing only
