Nice image. I like the coloring effect you used on the image. I do think that there is too much negative space at the bottom of the image. The image would look a lot more balanced if this part of the image was cut off. Good job.
I like the sort of "calm before the storm" feeling of this picture. Originally I felt that there was too much lawn and it could have been cropped closer, but I think that would have actually lessened the interest. Feels almost timeless. Happy birthday! :)
Nice use of negative space, it really gives the illusion that your lawn is immense. It looks a bit skewed to the right, and the bright white awning is calling a lot of attention to itself. It may have been a better photo if that one wasn’t there.
The grass at the bottom of the frame works like negative space, and is moderately effective. Your picture captures the feeling of anticipation... I really like it!
