I am no expert on the art of photography (though I dabble from time to time), but it appears to me that you have a very good eye for it. I am impressed by the skill you have showcased in your portfolio. I particularly liked the "Lonesome Prarie" gallery.
I am so proud of you for never letting go of your dream, and I am inspired that you made the decision to achieve it at a time in your life that many people may have given up on it. You are living proof that it is never too late to accomplish what you want most out of life.
Good luck with everything, though I suspect you will not need it!
