Hey, Larry - They are just getting better and better! Very nice, buddy!
One suggestion: If you want to avoid the tender mercies of the forum preview generation software, I suggest you down-rez your images yourself in PS. You'll be much happier with the results.
Also, with your work getting so good, you probably shouldn't be posting full rez versions. Just post your own down-rez'ed version (longest dimension less than 700 px) and you kill two birds with one stone: better quality AND image protection (nobody can do very much with a 700 px image other than view it on the web).
To let you see the difference between auto down-rez'ing by the forum software and DIY in PS, I down rez'ed your image and attached it below. I also lifted the shadow areas a bit to see the browns of the horse better. I also added a bit of grain to give some texture. See what u think.

PS - Arghhh. In retrospect, I now see that I should have just lightened the horse, not lightened shadows everywhere. Lightening all shadows mucked up the nice shadow work you put into the LH tree. Anyway, it was just meant to give u the idea, not be a final version.
