There is so much great art out there that I did not know which one to chooses from. What I ended up doing was picking a number and then going on YouTube and going down the list till I got to the number I picked. The tutorial I ended up on was a reciprocal gradient mani done by SimpleLittlePleasues . I have never heard of this and when I saw her cover image I was hooked to try it. Mine does not look as sharp as hers, but practice makes perfect, you can check out the tutorial here.
