What errors do I need to possibly fix in these?

Lets see how they look now.

Hi,

Your images either were rejected for:

1. Over Processed / Bad postprocessing, Dark / Underexposed
2. -
3. Backlit
4. -
5. Bad Composition (bad framing / aircraft not centered), Dark / Underexposed, Undersharpened (Soft)
6. Dark / Underexposed
7. Dark / Underexposed, JPG compression artefacts
8. Dark / Underexposed, Undersharpened (Soft)

I would start by addressing the rejection reasons given. You should also be able to find these in the email you received and the 'Photos' section of your member page. That way you don't need to post here asking about them.

The second and fourth don't have any record of being rejected recently, but the fourth is obviously backlit, so I imagine that must have been one of the rejection reasons.

Crop is borderline, but quality should be ok.
