Yeah. Cool. Nice and soft.
If you ever wanted to, some people like to polish them up with some contrast, highlights and back lighting. That would be focusing on the "fool the eye" also called trompe l'oeil way of painting. That's where they exaggerate the translucency and textures to make them seem very sensual. But there are all kinds of grapes and many have a matte surface.
So if I were to suggest something it would be to think in terms of lighting. Imagine a 3/4 direction for your light. That way you can use the artist's tricks to show volume with highlights and core shadow. Also if you darken your shadows right away it will tell you if and how much to lighten the rest of the grapes if it's necessary or not. But again, it's a matter of taste. I love lighting and tend to push contrast because it's fun and effective. But it's certainly not the only way to emphasize elements or composition. But it gives the eye some interesting variations to keep it lively.
