no illustrator just photoshop to make that splatter like circles/shapes I made them with the pen tool then liquified them
nic i do like the pen tool, but it jus seem it could be done with a brush like to get the same effect, i like the colours and i think the ring thingy on the left could be a lil cloer lol, i know its jus a tiny lil thing but for me it may make it look better. nice colours though
