I like #1, the orange of the flower against the green is very nice. Sorry, but the shallow DOF doesn't do much for me in the other ones.
Very nice shots, eNo! Specially the first one with the single flower, the harmony between the color of the flower and the background is amazing!
Thanks for sharing a touch of spring eNo. It's pouring down the snow right now, for me.
I really like the first one. ( Maybe even more with a little of the top cropped off.)
Great focus on the subject flower, and it's a touch brighter than the rest, drawing the eye to it. Well done!
The others are just a little bit too shallow in the depth of field for me.
