The plane looks good. If your CG is setup right, I see no reason that it shouldn't fly great.

Here's someting I've learned about rubber band wings. Never put any fewer rubberbands on the wing than you plan to fly with. I once put 4 bands on my DPS just to hold the wing on for a CG test. Two days later I took it to the flying field that way and actually took off and flew it with only 4 bands. I realized I had a problem when I could see the fuse slap back up against the wing at the bottom of a loop!
