Once i had made my custom brush now i can paint with it in different ways. To view the options better i clicked window and then opened 'brushes' this gave me lots of different options and settings for my brush. To create this image i changed the main diamter of the brush. i turned up the scatter so the swirls were more far apart. i changed the hue and saturation to vary (Thats how i got the different colours) lastly i adjusted the brightness jitter so it varied everytime i clicked. finally i clicked around everywhere. creating a really different textured pattern filled with swirls!
