Not bad for a snapshot photo. A little cluttered feeling, maybe play around with saturation to bring out the purple in the flower? Not a bad start though :)
I have these flowers in my garden in Romania too and i Know them as being a little bit darker..they have a nice shade of violet. I think the light was too strong and maybe you should have tried to capture the flowers a little bit better...they are prettier from the front.
I like how you can see the brown leaves and the contrast they have with the green ones.
