Looks cool, though I'm not a big fan of the Bevel and Emboss on most of your designs, could you try to make some without it?
Overall It feels like you were experimenting with a lot of different effects and I believe the outcome is decent for a signature. I have criticism to improve your design and hopefully future work. Don't take it too negatively. I'm only suggesting methods to help you grow. Critique The "vouches" doesn't feel right. It doesn't have the same green, has a different texture, lowercase V, and doesn't blend with the rest. You could improve the way it meshes with the rest by removing the bevel, experimenting with other colors. The overall color theme is being thrown in every direction. You have way too many colors clashing, and the green seems drastically dark compared to the image. I feel if you focused on her bathing suit's colors, it would be a lighter theme, but better looking in theory. To keep the darker theme, I would have suggested changing her bathing suit colors or choosing a different render. The black grass brush might have been better with some of the colors from the sparkles. Her hair is super darkened, near her neck. It is typically a poor idea to make sections of a graphic that horribly dark.
