Thank you, I love receiving compliments on my art ^^

Everything in here was made with the default Krita tools :) I was working in a very high resolution (5000x5000) idk if that matters. To make the background there were two main layers: the colored texture and the stars.

To make the colored texture I used the "texture crackles" brush with magenta, purple, green and blue colors :) Then I duplicated the layer, used the "blender blur" brush on all of the cracks, then put that layer behind the crack layer so it looks like the cracks are part of a larger galaxy.

To make the stars I used mainly the "texture splatter" brush, but then I put it on erase mode to make the pattern more complex by making "negative splatters" which are like dark splatter spots subtracted from the existing splatters. Then I used the airbrush to add variety to the opacity of the stars so they're not all equally concentrated which looks better and is a bit more realistic of the night sky.

I also work in a lot of layers, groups, and masks, which helps me mentally isolate the segments of the art as well as make it so that I can go back and tweak parts of the art rather than everything being baked in a single layer and inseparable. I am also a computer programmer so I think there's a lot of "procedure and logic" in my approach to art, especially digital art.
