I agree! I looked twice but there's no area of oversaturation even in the yellows...nicely done! The entire thing moves from warm to cool tones and I think that's what makes it really unique. Only small suggestion would be to include a tiny bit more frame at the bottom so the one petal tip isn't cut off but that's a pretty small nit.
I made a few changes to offer as options for you to consider... a slightly cropped bottom and right side along with a slight burning-in to the lower right and slightly increased sharpening.
Absolutely gorgeous image. The thumbnail does no justice to this beautiful frame. Liked the subtle colours & the spiraling pattern of the petals edges.
