Looks good Nick!
I might suggest a bit or reinforcement at the little gear hooks inside to take the stress and protect the main seam.
I would take a 2.5" dia circle of silnylon and bond it to the outside over the hook area. Just use SilNet as a glue. Then after it dries add a little zigzag / bartack stitch to the small ribbon holding the clip. Stitch it between the two main sewn lines of the seam so it puts the stress in the middle of the triple rolled seam.
Looks like you are already using small bungee to clip it all up.
