Sparkle, shine, glitter

I was playing with one of my phone picture editing apps and came across something that pixelates in dots not squares.

I turned it into a black and white image, then added colours with a flood fill option in another app.

I did more to it by using my phone editing suite. I went to the curves section which allows you to adjust the colours and brightness and adjusted it to make it more interesting. 

I’ve ended up with a dotty abstract.
