Pleasant clear sky

Canon EOS 60D, Tamron 18-270mm F/3.5-6.3 Di II VC PZD (50mm, f/5, 1/1000 sec, ISO-100)

I took a photo of the sky from Yoyogi Park. On  the grass right in front of the direction board stand the trees remarkably higher than the others. Trees get darker in contrast to the bright sky. When I put the high trees in the center of this photo, the other shorter trees appear as if they were the ground. This is how it looks to me.
