The 1st image is oversaturated, and the subject is not in sharp focus.
The 2nd image is underexposed in the shadows and has a white balance issue
The 3rd image is underexposed in the shadows, has a white balance issue and chromatic aberration
The 4th image is underexposed in the shadows and has a white balance issue
The 6th image is underexposed and the foreground has too much black which won't print well.
The last image is underexposed and way too blue. The sky is blown out and the verticals are leaning.
Hope this helps.
