Just a thought - I'm a bit jaded i admit - but the image is done in a low key manner. With the action that's being portrayed and the sun being bright enough to cast such strong rays, just feel that upping the contrast a bit and making the colors, especially of your lead character more vibrant and saturated would give the image more "pop". Keeping the shadows growing ever darker as they go back into the mist behind your critter, then having the scene become brighter as it comes toward the viewer might also give even more depth to the scene.
Composition is good as is the capturing of "the decisive moment" that grabs a viewer's attention. Not wanting to sound critical of what you have done, just wanting to give a few ideas for consideration.
