Those are very good names! there is no problem in letting your thoughts simmer. You can use one of those names, and if you ever think of something better, you can change it. My OC had gone through several major changes from his name to his profession since I created him.
The only thing left is the cutie mark, which is kind of the culmination of everything else. People often make the cutie mark directly related to the talent, but you can also base it off her personality or name. So, if you name her Vanilla Swirl, you can have a vanilla flower (which when I think about, would work very well with her color scheme), or you can work a swirl shape into the design. Maybe you combine the talent with the name and do something like a pencil drawing a swirl (if you decide to make drawing her talent. The only thing I should tell you as a warning, is that you should not make it too complicated. When it comes to cutie marks, simplicity works well.
