Here you got the focus right and a nicely blurred background so the flowers stand out. The colours are nice, too ... looks like it was an overcast day? Overcast days suit flower pics better (in most cases), so you chose the right day.
Yet, I think the background is very bright and the roses look too dark in comparison. Have you tried another frame with that stretch of trees (only just about to be seen on the lefthand side of your photo) as the background for these roses?
