The upper wing "spar check window" is in the wrong place too. It's set too far back.
Best picture I can find for comparison:

Not a massive problem, 'cause the raised edge to that window is also wrong. So it should be sanded off and re-sited in line with the main spar.
How Eduard got this wrong, I don't know...
