Hi Kakukk!
Looks good, but if you add camouflage you will notice that it's too glossy. Highlights are too strong!
The propeller blade shadow on the spinner can't go the way you have drawn it. It must be the same angle as from the horizontal tail on the fuselage. On the engine the shadow is fine.
Also I think the bulge on the MG cover (fuselage) has too strong lights and shadows.
Cheers,
BTW: Are you sure about the wing shape (wingtip in special)
