I really like your initial shot, with its wide angle motive, though it is easy to see why it falls foul of the A.net rules, as the subject all too easily looks very focused on the right. I am surprised you didn't get a level rejection for it as well though, as the second image looks straighter (having been rotated CCW).
I agree with Peter that you may have to sacrifice your initial motive and go for a wider crop - assuming you have it in the original. If so it will be improved further by including the whole of that tank, as he says, so you will then have the canopy closer to the middle of the crop.
Nice image - well done for trying
All the best.
