So if I may

1/ the window is not flat so shadows are completely wrong
2/ too intensive shadowing on the interior
3/ no shadow at all? at least on the lower part there should be some darkening...
4/ the lines look like hand drawn...i do not like em

5/ the shadow of the engine on the fuselage is missing...it should be there, as the angle of your reflections shows that it is not direct 12oclock sun...
6/ red fire extinguisteh plate is missing here I guess. or show photos that it wasnt mounted

7/ again the bulb on the glass was not so bulby

that it should have such a reflections...
nice profile..I am battling with B-24 a lot...cos my PC is not able to work with it

Zamex made me 1:19 or 1:9 lines...so MONSTER
And finally, reconsider the glass colour...it is too darkvioletosmething..I do not like it...
