My eye goes right to the center of the photo, which IMHO pretty much means it nailed the challenge. For what is essentially an abstract image, that's phenomenal! :) The thickness of the border complements the thick dark lines in the composition.
Great abstract and I love the dof you have used which has given gentle forground bokeh and really strong background bokeh with, sandwiched in between the very strong tones and sharpness of the leaf
I thought the border worked really well on this shot
I don't quite consider this centered comp. Even though the joint of the leaves is in the center, it does not lead the eye there. But, I can see your interpretation of the topic and I do really like it.
It's a really interesting photo with grat tones, but what exactly is the subject? Is it that joint where the leaves come together? WOuld look wonderful framed, but rather unitriguing. A ladybug, or droplet of water. Why focus on that point right there? this only IMO. I think technically, you have photography nailed!! Let the photo tell a great story though.
