I would reply, but it appears that the Flickr uploader system is currently down (I was about to add something from Saturday).
Btw, the poor Chaffinch isn't the first thing you notice in that shot (despite it being a nice sharp image of said birdie), it's the damn bokeh.
Me being me, I'd have just taken a picture of that curiously scratched branch and the eerie, unsettling bokeh field behind it...!
But that's just me!
Nice idea (more crazy bokeh blobs!) plus Square format is good
Did you take a version without the tree trunk in the frame?
Personally, I think it would work better as a composition just as the flowers in the foreground and the distorted OOF stand of trees in the background, but hey, that's just my opinion
