Perspective on a fern leaf

I like photos using angles such as this, although this is not a particularly good example.  I took this photo with a semi-automatic camera at an extreme zoom, so the depth of field was compressed.  

Typically it is preferable to focus on the foreground when depth of field will be limited, which I did, but I think having the center of the photo out of focus is distracting.  I should experiment more.

This week we have photos of some examples of the extensive, high quality street art of Valparaiso, Chile, posted on our Viva la Voyage travel photo site.
