Hi Mark. Welcome to the Macro Forum! You did a nice job with your stack (something I need to learn
). Good sharpness on your millipede. I like the soft, even light and the water drops on the millipede add a nice touch. There are a couple minor tweaks to the background that would make the image even stronger. The OOF bright water drops near the ULC are drawing my eye and they would be easy to clone. Also, you might consider blurring some of the mostly OOF elements in that same area of the image as they, too, are drawing my eye.
Overall, this is well done. I hope to see more of your work.
