I also love the concept and think it could find a ready audience, but my initial reaction was that the fuselage and boom are a bit too complex. I think that coming to a point at the bottom of the point-down triangular boom and then going back out again for the rest of the triangle makes the structure very busy.
I would use the triangular boom from engine to tail but base down, point up (except in the last bay at the tail the two base tubes come together at the tail post). You could move the horizontal stabilizer to the bottom of the boom if desired and even have a triangular fuel tank. Now the top of the triangular truss forms the attach points for the wings just like triangular cabane struts and all the "frames" that form the sides and back of the fuselage can be simple rectangles or trapezoids with X-bracing or corner bracing. The seat back, for example, would be a single rectangle or trapezoid all the way up to the bottom tubes of the truss.
Another approach would be to eliminate the triangular truss boom from the forward fuselage, and instead bring everything to a point like triangular cabane struts, then built out the existing triangle behind the pilot's head to form the boom for the tail. This reduces the parts count considerably but does't really work with your engine location. It would work with a paramotor engine as a tractor on the nose of the pod or a pusher behind the pod. Taken to its logical conclusion you end up with something all triangle like Ed Fisher's Flitplane.

I removed a few pieces of tubing that now that you mentioned it seemed redundant. I really dont want to build a parasol as I want to be able to attach doors and close it in and it is higher to allow for better forward view under the engine. Structure behind seat for float mounts or tricycle gear maybe. I would build it in 2 pieces boom upside down flat on the table and cage with the floor flat on the table then suspend the boom over head and bend in the cabines cut fit and weld. Current weight for fuse tubing is 32 lbs wing aluminum is 28 lbs.
