Valuation model (DCF/Comps)

I'm pretty new to modeling and thought I'd give my shot at valuing Apple. Would anyone be willing to take a look at a valuation model I did as practice (ideally someone with advanced modeling experience)? This is my first time doing a full 3 statement projection, comps, and dcf and would really appreciate if I can get some feedback. 

I will PM for details if you leave a comment

Thanks so much in advance!!
