Hi Mara,
Technical issues may be in “vastly different pictures”, errors are not subject dependant. However, you should limit the posting to 2 to 3 pictures a time. It takes time to analyse the pictures and after a while, you will be able to do that on your own.
4973: Missing contrast, noise. Photographing into the sun is difficult and needs some editing as the sensor dynamics will not keep pace with the subject. It helps to set the ISO to the lowest possible value here.
7724: Out of focus and chromatic aberration.
0991: Chromatic aberration
and white balance. In addition, you have an IP problem (name of the ship, several logos) and you need to supply a model release for all people recognizable in the picture.
8331: Out of focus, noise, white balance and underexposed. Look at the histogram. Highlights and whites are missing (right part).

0491: Colour noise, probably is the DOF too narrow.
5338: Out of focus, underexposed (look at the histogram), noise. There are also multiple IP violations (name of the ship, pier number, several logos like Coca-Cola etc).
3004: Out of focus, noise, B&W. Don't convert your pictures to B&W, as most of those will be refused. The customer can easily convert to B&W, but he cannot get the colour back.
6221: Out of focus, chromatic aberration, noise.
Look at your pictures at 100% and 200% (sometimes 300%) to detect image defects. If you see them, correct them. Out of focus cannot be corrected. Logos and other identifiers are IP violations and get you a refusal of otherwise perfect images. Model releases are needed for recognizable people. Property releases are required for recognizable properties (ie pictures inside a house).
