@armentor, Beautiful pictures for sure, and as soon as I've saw these pictures then first thing which came in mind is Beach Volleyball after watching that net. And beach volleyball is really preferable sport in summer.

And in second picture if we carefully watch towards sun then for sure we can see that there is an lite Red effect is creating which is slightly bending and overall impression is like an Bird Wings.

Wishing you an great day and stay blessed. 🙂
