You'll gain a bit of cleaner and more accurate airflow if you extend the upper sheeting about 1" past the rear edge of the spar. Doing so should perk up the slow speed flying by delaying or avoiding the often typical separation bubbles that can occur right at the edge of the LE sheeting when it ends right at the high point where the spar sits.

This was a common improvement done on some early designs that used the E205 airfoil.
