To OP,
You're not in perfect situation as others said to jump to TH9. Though, your TH8 is quite mature to go, with max Mortar, HT, Cannon and soon-to-max WT & AT. Lv5 Barb King is also not bad. Lv91 also means you spend enough time at TH8 or maybe you just donate a lot.
With lots of skull wall, it seems that you have good farmer skill. With a bit more patience, I believe you will spend not much time to get all skull wall. Seriously, why don't you spend those Gold to upgrade all walls to purple instead of some skull wall?
Lastly, my nitpicking is your builder schedule. You will not have all 5 builders available when you reach TH9.
PS. Saving 40,000 DE to instantly buy Archer Queen is the most crucial thing when you reach TH9, in my opinion.
