Very nice image, especially the sky! But the render seems a bit weird. It looks like you've rendered 1280x960, which is the limit in the unregistered version, then scaled it to 1600x1200, and blurred some of the jaggies. Am I correct? :) You might consider just leave it at 1280x960 and do a more subtle smoothing of the jaggies.
John 3:16
" For God so loved the world that He gave His only begotten son, that whosoever believeth in Him shall not perish, but have everlasting life."
