Good start indeed. Welcome to the world, or the rabbit hole, of macro photography.
Your stacking software did a pretty good job of resolving objects in different focal planes, or perhaps you did some retouching in photoshop afterwards? Well done if so. What stacking software did you use?
In general, stacking tends to bring out a lot of extra noise, and the final image can benefit greatly from de-noising. Topaz DeNoise AI is good, but there are other options too, I'm sure.
You may start looking into close-up attachments such as Raynox DCR-250 or NiSi to get more magnification!
