While the tilted horizon doesn't really bother me -it may add dinamicity to an image in which the horizon is not a central matter- I find quite bothering that trees behind the man's head that should, on the contrary, be the central subject with that hat. About blurring: be careful, if the image you upload is larger than 640 pixel in oned direction, Usefilm will reduce it and a loss of quality is expectable. Try to reduce it before uploading...
