Technical issues regarding

0143: Flower pictures get vetted more stringently than other pictures. It's missing local contrast, if you look at the blossom you see artefacts due to the sensor and lens limits.

1924…: is overexposed, and the face is not exactly in focus. If you have this as a raw shoot, you may try to save.

0037: This one is over processed. Too much sharpening and noise reduction destroyed this image.

937: The horizon needs to be straight (the sea runs dry… 😉 ). The white balance needs to be corrected to warmer tones. You may apply some local contrast and light sharpening and with those corrections try submitting again.
