The way to post a photo that's hosted on Flickr is to go to the photo page, click the Share drop-down menu above the picture, click "Grab the HTML/BBCode", select the BBCode button, then copy the code in the box and paste it into your post here. I've done that below.

Since your subject is the jetty, I'd say that the focus is fine. The grass in the foreground looks slightly out of focus, but that's to be expected when the grass is blowing in the wind. It's called 'motion blur'.
