In the last pic of your wing, it appears that your shear webs do not contact the sides of the ribs. Is there a reason that you left those gaps instead of filling them so that the webs would contact the ribs?
The manuals for the kits I have built (three, working on a fourth) have all said that shear webs do not need to be glued to the ribs.
Here is a quote from page 13 of the Great Planes Corsair 40 manual:
D D 10. Install 1/16" x 3" x 1-5/8" balsa shear webs (W11) on the aft side of the spars from T-1 to the wing tip. Install one extra shear web on the forward side of the spars between ribs T-1 and T-2. Use medium CA and be sure to get a secure bond. It's not necessary for the shear webs to be glued to the ribs.
On the Corsair I did make the first shear web (between T-1 and T-2) fit the ribs so I would have a closed pocket to hold the epoxy when joining the wing panels to the center section. All of the others were just glued to the spars.
