Nice your getting alot better, but it needs more colors, add some light purple in and smudge them, that layer to something that dosen't make it stand out much, but you can still see the purple, you can repeat that with any other colors you like, but this, i have to say, is your best yet
i don't know CS1, but i think there is a tool in there callen the smudge tool, if you make a new canvas, or something, there maybe a thing at the top called, tools, click it and if there is go down to smudge, like i said i don't know CS1
