Hi Gigo and welcome to ThePhotoForum.
You do it all right: flowers in the Nature Forum is just the way it works

.
And you know how to nicely frame a flower, I can tell. The colours are a bit off in the first, from what I can see now, but I am sure it is because of the scanning process. That scratch ... is that on the print and maybe even the negatives? (I would hate the lab for that... ) I don't see the scratch on the other two.
Of all the three I like Photo 2 best, the colours look best there and I really like the background (the bokeh - do you know what that is?).
