You’ve got some good bits in, but the mid portion of both the left and right side of your loop are going in the wrong direction in my opinion.
You’re better climbing Rowlee farm, then descending Lockerbrook, then following your loop up to Cut Gate.
The Cutgate portion is ace, and there is a nice pub with beer garden on the main road in Langsett for your pub stop, then on the return leg when you get back to Ladybower end climb up the slabs to Whinstone Le Tor, then descent Jack Bridge, and down to the Ladybower inn. Then finish your return leg.
It’ll be a good loop, Cutgate both ways is my favourite bit of Peaks trail.
