Fucking loads of straps, but it's always going to be a compromise. I can presonallyy recommend not attempting to reattach it to your bike at 4am in Dieppe in horizontal rain.
Looks to me like you need more strapping, further up the bag. Also, maybe experiment with packing it different ways/with different stuff for more rigidity.
