Indeed, there are areas slightly brighter than pure black. I think I need to fix it with GIMP.
Even with a profiled monitor some will show blacks as brighter or darker (same for whites). If some areas are not quite at 0 or 100%, some might see spots you did not.
If you're intent is to go completely black/white, it can help to add a temporary Levels Adjustment layer.
Turn it all the way to one side so the blacks start going white. :-)
As you get there, you'll quickly see areas that are not quite black that probably should be. You can then go back and paint in these light areas with black on the original (or even better, on a separate layer).
Then finally remove the temporary levels layer and your background is perfect. :-)
I often have more problems with whites than blacks. Sometimes quality prints will show the higher shades of near-white when my monitors did not.
Anyway, I like the image.
I would probably have put a reflector underneath to the left to open up the shadows a bit.
A little spot cleanup of the dirt and debris on the petals would be good too.
