Very nice work, Sasha. Good rich colour and well composed.
While it does add impact, throwing the background out of focus,with flowers of this size, and a close background, is a bit more difficult, and requires manual conrol of the aperture
to get it precise. You did an excellent job with this.
I like the color in this shot. The flowers seem to be a bit to sharp compared to the background, Try making the background less blurred - or try to soften the look of the flowers. Other then that I like it. I hope that this helps you in some way with future shots. Cheers!
Thanks everyone for all the great feedback, and especially the comments for improvement. I always love seeing anyone give me suggestions-- I've got a lot to learn!
