I hadn't seen this color variant of Black eyed Susan. Looks interesting. Probably needed a couple more frames to get the petals in the front in focus. top of the head also looks a little soft. Details look great.
Beautiful Colors. Pleasing Image works well with Background.
I never got stacking to work for this kind of flowers..
Not sure If I am missing something.
The ones we have over this side of the pond are yellow. At least the wild ones anyway. Pretty neat to see a red one. The stacking worked nicely. I like that you didn't clean up all those petals. Shows it has some age.
