Image quality issues

Lots of noise and no sharpness. Also in the last photo there are very black shadows and overexposed highlights. What did you take the photo for? On the phone?

You have exposure and contrast issues.

The histogram for the first shows missing highlights (right) and a small part of the blacks missing (left):

You have colour noise in the shadows. Your white balance is off. The main subject is not as sharp as it should be, pobably due to noise reduction of your camera.

Your second is similar.

Your third has more contrast. It has, however, blown out highlights.
