Beautiful, but a bit dark. You need to adjust the levels to bring out the details below and to the right of the Tulip, but you'll have to apply a protective mask over the Tulip. This can be done in Photoshop. For example, in the VK editor, you can move the "Exposure" slider to see what I mean.

No, there's no need to pull anything there; the signal is distributed evenly as it naturally exists. Saturating everything in red doesn't make sense to me—it's visually unappealing. I've tried many variations, masks, and processing techniques. This version best reveals the desired depth and structure.
