I like it!   One potential problem is the bent trailing edge as that requires a glue joint and creates a potential weak point.   If I were set on doing that I think I would do a long tapered joint to maximize the gluing area or consider extending the center sheeting out far enough to go a rib bay out beyond the bend.    Also I do not know what you are using for power but that is a pretty big wing for a sport 1/2a like a Cox or Brodak 049.   It might be okay for a Norvel or other 061 engine.     If I am seeing correctly your wing is the same thickness out to the tips.   That actually is a good thing as it helps avoid tip stalls as the thick airfoil at the tips would stall later than the center section.     I have had some very interesting problems with airplanes flown in overhead manuvers falling in on me due to tip stalls.
