Tough conditions with regard to lighting and subject matter, so applaud you doing the work and practicing in the frozen tundra. It's hard to be steady when your freezing!
- Really like the color and contrast so it looks like the white balance was correct
- Focus is solid
- There is some background separation with the DoF
- Agree with prior post on composition. Perhaps getting low, putting the subject on the right third so there is more travel distance.
- Easy to write but harder to do ... Capture a moment. This looks like it was on an average stretch of the course. The more dynamic parts of the course (start, finish, tough hill climbs, or rough terrain) will generally give you greater opportunity to capture a great expression which helps draw the viewer into the moment.
- A post treatment may lend itself well to this type of a shot to help grit up the athlete or tone down some of the distracting elements (yellow pole)
Overall if I were the parent or friend of this runner I'd think this image is great as a documented moment in time. As an event, sports photog, or artistic piece the above are a few things to try.
