I'll take a look.
Thanks for this, clearly nowhere near as good as I thought I was and I have a long way to go.
Apologies for wasting your time!
In several of your photos there are also artifacts and chromatic abberation visible.
When you take macro-type photography you must make sure that the background is sufficiently out of focus, very little depth of field, a large diaphragm opening, and so that the lighting is not burned out, you may have to use a very blurred flash that illuminates the object well, but not the background, especially for this type of photos it is best to use macro lenses to be able to have advantages of speed and diaphragm, especially in insect photography
Thanks for the advice all! I'll take it all on board and improve for the future 🙂
