Looks good to me, but since you asked...
I've never used camp shoes, so they're not on my list - that'll save you a pound.
I do carry a fleece and puffy, some don't.
Trade the z-seat for a 1/8" thinlight pad. Does everything the z-seat does and much more, for about the same weight.
Trade the REI rainwear for Frog Togs and an umbrella.
Some gauze and tape or at least a good bunch of bandages.

Here's the list I used to get my base under 15 pounds: https://www.backpacking.net/27-pound.html#pack
