Further to the comments from @Abambo :

Offset_Porfolio66.jpg - underexposed

Offset_Porfolio61.jpg - soft focus, white balance (too blue), underexposed shadows, and chromatic aberration around the skier

Offset_Porfolio55.JPG - significantly underexposed; learn to use the Histogram

Offset_Porfolio55.JPG - underexposed, not sharp

It is customary to upload just 2-3 images here for feedback, which are usually sufficient to reflect the technical issues in the entire batch. Few volunteers here will want to take the time to comment on 10 images.

Offset_Porfolio71.jpg: Noise and slightly exposure (noise was the problem).

Offset_Porfolio68.jpg: noise.

Offset_Porfolio68.jpg: noise.

Offset_Porfolio61.JPG: noise.

Offset_Porfolio57: noise, exposure

I won't look further. For noise reduction, you should use the newly developed raw noise reduction in Lightroom. In addition, you could check this: High ISO noise reduction
