@teriyakih I had never done one before the challenge. I found an App called Circular. It was less than $5. I select a photo I have taken and then just start playing with the image edit sliders. When I like the effect I added a filter in the same app on some but not all of them. It is really fun to just start playing around with the sliders.
It does indeed look like a bird. Wings of a dove springs to mind. You are inspiring me to look at some old photos again and turn them into a little planet. I have done a few earlier in the year.
