with the other two star brushes, just add in some more stars. just mess around with the brush settings until you get something that looks a bit like this:Ĥ. firstly I took star 3, set the colour and hue jitter to about 50, and just randomly put some stars in the background- because these stars are a lot of different colours, you should make them quite big and put the opacity down. then you're gonna find the 'star' 'star 2' and 'star 3' brushes and use those. you can blur it more or less if you want to, its basically all subjective as to what you think looks good/ suits the rest of the drawingģ. click on 'filter' at the top and then on 'gaussian blur', then slide it until you get this effect. you can also leave some white spaces too it wont matterĢ. also, dont do any yellows ,or greens with no added blue, here because those come later.

remember, the range of colours you chose really matters here. put just pinks purples and blues if you want a less colourful galaxy, but I put down a lot of reds and greens so mine's gonna look a lot more colourful. with a very big pen tool, put down a load of coloured circles. This isn't niche fanart but I put it here because this is how I did the galaxy for thisġ.
