Blues and Purples Watermarble

I recently did another watermarble! I feel like all my watermarbles end up looking exactly the same. I think the main issue I face when watermarbling is that my polishes spread out too much and the colors end up really light. I used China Glaze Let's Jam, China Glaze Plur-Ple, China Glaze Boho Blues, and Xtreme Wear Royal Hue.
