I like the composition, except for a few distracting things: (1) the front out-of-focus flower, (2) the dead leaf, (3) the BG wall, (4) centre clump of grass + twigs(?) + brown bits of grass. Also, the pic could do with rotating anti-clockwise to level out the BG brickwork.
A bit of 'gardening' could have cleaned up the ground-level, but to me the whole image has a lot of clutter - bits that do not enhance or contribute to the image (all mentioned above).
If you could have gotten closer to the group of flowers which are to the left of the FG blurred flower, you'd have filled the frame with just flowers + stems, + this shorter distance between the subject + camera would also have decreased DoF to help blur out the BG brickwork more effectively.
As always, just my own opinion
and of course, I could be entirely wrong in my projected results per my suggested approach. I do envy you all the practice you're getting in at the mo'
