Beautiful image and excellent technique -- really a lovely photo!
Acerola's comment brings up an interesting point, that viewers may read more into an image than the photographer intended.
Most insect eggs do get glued down, crammed in a hole, or otherwise fastened in one place.
But stick insects are special because they just drop their eggs and let them fall to the ground, bouncing off leaves and twigs on their way down. (My rearing containers used to sound like a gentle rain, when the gals were really getting into it.)
So, if you could make it work, a good way to photograph one of these eggs might be to find some photogenic dirt or ground litter, just drop the egg into it, and shoot the whole mess as it sits, no glue.
It's hard to do that with a horizontal camera.
But maybe you can fasten your milling table to a piece of plywood or something and tip it up to shoot down? (Just be sure it doesn't fall!)
