This is an awesome picture! My biggest suggestion, tho, is be aware of your size! This is HUGE, and not in a good way. My resolution is 1920x1080, but at 4960 pixels wide, I can't get even half of this one my screen. Even with a 25 inch widescreen monitor, all I get is a red stripe thru the middle of my monitor, and that's it. Plus, loading time was long due to the large file size.
Great picture, but try to shrink it down about 50%. :)
