Need advise on the reson for photo rejection

DSC_3329.jpg: Not really understanding the randomness of the objects and how they correalate with each other. That said, the highly are burned out and the glass with water is crooked.

DSC_0419.JPG is a nice picture. I guess it's Australia. You should have chosen to get a better DOF. In addition, I would get rid of wood sticks and plants distracting the view from the main subject. We are not working for the National Geographic here.

DSC_0583.jpg is ill framed. You should not cut off the rope mountains. The bridge or building in the background is disturbing, the DOF is not great, the ropes in the foreground would also need to be in focus. I have the impression that you excessively sharpened your asset. One consequence of this is the light-coloured outline of the ropes at the sky transition.

Checking those 2 images and especially the out of focus areas, I think that you are sharpening too much. The out of focus areas look like someone has tried to bring up detail there.

DSC_3319.jpg The scene is overexposed. Getting the exposure a bit down will bring back structure in the lighter colours. The composition is not good. I think you should let the cropping to the buyer.

DSC_0489.JPG: Nice beast, but there is noise in the background. The caterpillar probably needs selective development to work out the contours better. You should apply noise reduction to the background. It may pass then.

DSC_0419.JPG - when zoomed in to ~100% I can't find anything in sharp focus 

If you zoom in you can see the unnatural borders.
