Rainy days are amazing. You see droplets of water, running rivulets, maybe a few paper boat or maybe this amazing art. Oil mixed with water, and finding its own path along the road. (Looks like a browser window). And the thing that it was taken from a height, gives it a different look.
See what difference perspective can make!! So go outdoors and keep shooting.
This particular shot was captured on Pixel 2 XL, and tweaked in Snapseed.
