Nice, Swamp.
I learned from the Ken sling, Anderson and my testing that you can build up support (webbing and thread but don't know how to say it) that work very well. They will keep the three horizontal pieces of webbing forced to stay separated. I don't know if you are having the issue where it wants to bunch up under you, especially on the ends. Having your loops come off like that, under weight with a carabiner it pulls the two ends together. So using a different method of attaching to your bridge or reinforcing the ends has proven to help me.
Again, not sure if it is a problem you are having but if you want I can send you some pics of what I'm referring to. I see you have a piece of webbing that extends differently than I've seen in others which may already be serving the same purpose.
Looks really cool. I have a hammock concept that I've been playing with in my head too. Maybe we can nail that idea and make millions.
