Good job.
I also did my floors first before insulation.
I wanted to mention for everyone's benefit that when it comes time to be on the ladder to have someone bracing the bottom. The ole ladder 101 thing.
What happened to me was that I was at the top of the wall installing wall board. Between the slick floor and construction dust the ladder decided to slip out from under me. I, hanging onto the ladder, took a jarring ride down the wall.
No hurts but it was a spooky, oh c*** moment.
I suppose it would have made a good "can't fix stupid" video. Bump, slide, bump slide, and so on all the way down.
An appropriate hard to slip rubber mat under the ladder may also work. In hindsight a scaffold would have been the better, safer tool.
