Depending on how shiny the reference surface is, you could push your highlights more and emphasize reflective glare

I would deepen some of the shadows to up the contrast so it’s on the same level as the flowers!

If it were a smaller part of a bigger painting I'd say it's perfect. But the painting as a whole I think isn't "abstract" enough to justify the lack of texture on an object that’s the sole focus of the painting. (maybe add a bit of a third dimention to the top too if possible?) It’s very pretty though! I love the coloring and the flowers.
