Looks great. Just two thoughts.
1. I understand the best place for the drain pipe is on the footing as opposed two next to the footing. A convex "ribbon" of mortar at the retaining wall and footing seam could help keep water from undermining that joint. The reasoning I've read was the pipe will catch the water earlier and it provides great resistance to lateral movement of the footing.
2. I've had better finished slab results by placing 2 inches of course sand or fine gravel below the slab and above the insulating board. This allows the water in the concrete a place to go and slowly evaporate instead of puddling on the surface making it very difficult to finish in a timely manner and the surface water could weaken the top of slab significantly.
Any thoughts or comments are appreciated.
