Ouch
No, not so much … smiley asked for feedback on his design concept, and constructive criticism is what s/he needed, and got.
I’ll step out on a limb and guess that smiley is “new” to design and engineering, and probably doesn’t have too much hands-on experience in “mechanics”… YET. smiley, a few study scaled-down models would help you out a lot I think, say 1/8 actual size (+/-); they will help you get a grasp of the strength of materials and joinery details. They don’t necessarily have to be actual materials you envision in your concept to help you develop a sense/intuition for the mechanical problems one might encounter.
Consider: As thin as your “supporting arches” appear (as rendered) you can understand how they would tend to flatten out when a load in placed in the seat (without something (the term is: stretcher) to prevent the ends of the arches from moving apart). Now, imagine how much thicker those arches would have to be to resist that tendency without a “stretcher”. A simple design consideration really … if the desired effect is unsupported “arch” then they will have to be strong enough to resist the load; thicker, deeper section, etc.
The seat has it’s own issues … how would you make it strong enough to resist bending while still maintaining the light, airy, feel of that in your rendering?
Lots of stuff to learn. So yeah, it’s back to the drawing board… . you’ll be spending the rest of your life there if you intend to stay in “design”… 
Please keep posting.
