I don't know if you've realised, but the shadow on the wingroot is darker than on the rest of the fuse; it's not gonna look right. Also, it doesn't follow the shape of the rear fuselage. I've noticed the same with your Skymark A380.
Other observations:
-- the horizon reflection doesn't look right; it's cut too short at the nose and needs to circumvent the h stab
-- the US flag needs to extend to the edge of the 3rd window from the end and it's too tall
-- the reg font looks wrong; I suggest using one of these:

-- should use the old door frame style
-- you should squeeze the top half of the grey circle, not the whole of it 'cos the top will look too fat in the sim
-- red arrow looks too small
-- NWA titles alignment could be improved
-- SkyTeam logo is too big
