"Why is the ground on the right side of the photo?"
This is one of those roof photos where there is no good way to orient it. I just now tried to rotate it counter clockwise 90 degrees, and then the right wall looks like a flat sidewalk, and the left wall looks very overhanging. So I left it as is with the left wall looking like a sidewalk and the right wall looking very overhanging.
Or perhaps you were kidding about the right side looking like the ground?
I'm placing a good nut on top of a good (currently) fixed nut at the start of the crux. Above this you can get 1 or 2 hand-sized cams, but it's hard to hang out there. The crux is over when your left leg is stemmed out to the small bush on the left. The route continues more easily from there with right side into the corner/chimney and left leg stemming.
You can see from this photo that the big roof that looks almost horizontal from the ground is more like an overhanging corner.
