My vote goes to #2 Mosen, I think it is the picture that best illustrates the difference between spring and summer and I like the change of perspective it offers. And also to make him feel guilty for not voting for me. Also, please, don't let me win, I didn't think mine would be taken as a real contribution. I liked #4 Fellfrosch's too, but a little bit too much local contrast/sharpness for me.

(Yes Fellfrosch, I used the Pro¹ and I think the base Sailfish camera app for mine.)
