Nice subject, You could probably get away with enhancing colours as It looks like quite a dull day. Maybe a slight crop to get rid of a bit of background on left would work quite well as there is just a little bit too much and it makes the image slightly unbalanced. Its just my opinion. Its good though i like it.
I'm usually not a fan of these kind of photos, but the complimentary colors pulled me in.
The composition of the flowers is good, but maybe if you tightened the shot just a little bit more, it might have seemed more dynamic.
Regardless, you still captured quite a bit of texture in this image, and then there is that lovely, shallow depth of field.
