I use the simply ring macro flash Led lamp, is useful a bit hard to use to get good effects, but I think to create any good diffuser for It but it's too hard when it's on the lens.. but I can get quite nicely sharp subjects with external ring tubs ..
Maybe you are right, the temperature improving can be good

. The picture was a bit hard to editing and I I cropped a lot.., I can share the picture in original one day if you want to try to edit it or in Photo Clinic subforum.. hmm maybe someone will have an idea how to improve the picture, any magic

I think the forest maybe not best place to shoot extreme macros when there is lot of shadows but lot of objects to shooting too
Danke
