I've not see the DoK on the table yet, nor do I have the Battletome, so I can't speak for any of the Sects, relics and such, but, seems like a solid enough list.
The only major advice to give, is that you have far too many heros. In AoS, you probably don't want more than 2-3 heroes, depending on the cost. As, for the most part, heroes are weaker than units. Unless they can give units a substantal buff, then it's not worth stacking too much of them. Your list, has 680pts in heroes alone, which is crazy. I'd drop three of the Hag Queens for sure, as there is no reason you need 4 of them. A single hero is a good unit to leave behind on objectives if you have an agressive army. A ten strong unit of witches not getting into combat, and camping on an objective, doesn't help in any way. I'd use the points saved from dropping three hag queens, on buffing up that small unit of wyches, or Blood Stalkers. If you don't have the models yet, I'd build the blood seekers in your list as blood stalkers too. Mortal wounds on ranged attacks is always good. They are a fantastic unit to hold back with, and snipe characters.
I hope this helps!
