if you are doing it fingerpicking, it's gonna take a lot of practice. It's really tricky and you will have to place every words on every note (or silence). When I learned the Unforgiven, the hardest part was the singing part on the chorus. Kirk's part aren't as hard and the solo is pretty intermediate friendly I'd say! Good luck!
Sys, I really hope you finish The Unforgiven this time after inducing me to learn it to play with you and dropping it at the intro when I was almost learning it completely!
Yes I'm exposing you cause I'm still mad
Also your pajamas are pretty great, please use the Garfield pants
