Retrace a Backpack with illustrator and do a render with photoshop -- 2

I want to realize a render in 2D of the Extreme 2.0 Backpack following the picture that you can see. Start with drawing it on illustrator, create different layer for every piece of the backpack (example the front in one layer, the pocket one layer, the stitch in different layer an so on...) more are the layer better is the result, every layer have to be named!!! The shape of the vectorial path have to be the same of the piece that you are tracking. After illustrator develop the texture and the effect on photoshop (they will be different from the picture that you can see. I'll give all the information after. I'll give you an example of how the work had to be done. I want to do some revision during the process to control if everything is done in a correct way. Format: A4 file type: .psd .ai .jpg softwear: illustrator photoshop This request is mandatory, I can't accept a different method of work.
