Wannabe Artsy or Wickedly Awesome?

I took these photos out in my front lawn after school on Wednesday, and when I finally got them on to my computer this evening, I couldn't believe how well they turned out. It was so hard narrowing it down to a few to post, I feel I could have put up any of the 75 and been proud of them.

As you can see, I'm really loving the look of a short depth of field right now. One of the things I love about my new camera is how much more extreme this effect is. These are shot at f-4.5; and they depth of field is still like twice as shallow as my old camera at f-2.6. Some people may see that as a problem, but personally I love it!

What do you think? I am right to love a short depth of field, or does it look wannabe artistic?

Love,
Rosie
