It is a excellent foto, I dont know why you did not put it out in a bigger scale???.
There is only one thing in this one, the hoisont tilt a bit, 0.5, I have fix that and try to make your foto a bit bigger, pleace take a look. But I cant make a perfect foto out on your, but you can out of the orginal, then it vill not pixel.
Keep up the great work.........Regards Kaj Nielsen
