I agree to the left would be better, but originally I had the tail fin in as well so they were just to the right of centre, so not sure if a tighter crop would lose to much. I'll have a look tomorrow when I'm back on my Mac.
I had a go at shifting the guys to the left. To avoid cropping too much detail I shortened the missile to keep the rear fins in, stretched the right hand side of the plane to afford more space to the right of the men, and rotated the whole pic to level the missile.
That's my 'interfering busybody' deed of the day done for today.
