Just about done with PSR stage. Here it is with a coat of primer.
Purely from the real aerodynamics standpoint, the intersection of the wing and fuselage would not be that sharp or concave. It causes significant interference drag, especially at speed where compressibility and transonic flow are expected. That interface really needs a fillet to smooth out the airflow in that corner.
However, as Faithful Patsy once said, "It's only a model."
