I like the diagonal line formed by the fox emerging fromt the den. Looks like you had some tough light to work with. I think a tighter crop of the fox would help eliminate some distracting elements. The image needs to be lightened, the contrast boosted and sharpened...
Raymond, I agree with all the comments posted. You have found a special place safeguard it and you will have many more rewards. Your position to the den looks ideal.
Best,
