Very nice composition. Bon rendu des couleur (tout en douceur-soft colors). Nice use of back light.
Cette plante a une fleur ravissante!!! Du pur bonbon! Is it an easy plant to grow for you? I never tried, thinking it was difficult.
But I would say like SlipperKing. Grainy. Did you had sharpness? (accentuation, netteté).
For focus, I suppose you know that you can add depth of fied if you close diaphragm ? (OK... I am sure you already know it!!!!).
And sometimes, when my subject is close from the lens, it found it very difficult to get a sharp image. So, I move the plant black a little. Finding a good dept of field is easier when subject is not too close. And I « cut » the image with Photoshop. Of course, the subject should not be to far aways from the lens.
