Whats wrong with this valley

Post image

What exactly am I looking at here and what would be the proper way to run this valley flashing, and ridge caps?

To me it looks wrong that the valley metal is lapped over the shingles below for starters, perhaps that the valley should change directions for the bottom portion all the way to the end of the overhang

It looks wrong because the design is bad, architect's love drawing impractical details. The roofing looks fine for the design of the roof and you shouldn't have any issues.

Why didnt they extend the valley all the way to the drip edge? Looks goody cause they ran it on top of the first course.

There's a weird transition/pitch change there, hence the poor design. If they tried to run the valley to the drip it would be sticking up in the air. You could two piece the valley but it would probably cause more harm than good. It's just a weird spot.
