Water drops on cactus thorns

On the background of a cloudy sky, a part of a small cactus, with some water drops on its thorns. In the quite big, particularly reflecting, drop in the center, one can arrive to distinguish the sky (there is a bit of blue within the clouds) and the shapes of the surrounding buildings.The catctus appears dark, in the backlight. This is an enlargement of a part of the original photo, that is taken with a macro (March, 2018).
