It seems like you could have got closer.

not a close up

@ creative frredom. If you have an issue with an entry, please use the red flag system, that is what it is there for. Stating 'not a close up' is a red flag issue, and should be done that way, not in the comments box as you have here and elsewhere.

not a closeup

Above comments apply to the original image, which has been changed to one which is closer-up.

It's better and it's a close up now, but it's a little OOF. It's a shame you could not have created more of a depth of field by focusing in on two or three bricks in the wall with a defocused effect more one the ones farther away. Maybe something you might want to work on.
