Working on composition

One of the many things that I'm trying to work on is composition in my photos. To get a nice short depth of field I usually have to use our long lens (55-200mm). It allows you to get in close from far away and give you a more "intimate" feeling like below:


One thing that I love love love with photos are our "perspective shots" like this shot in Barcelona:


I'm now trying to play with this for what I wouldn't have seen as a "perspective shot" before. Here's an example from some pipers on the hill a couple of weeks ago:

It's funny, looking back at some of the pictures that we took with our old point and shoot, I'm quite happy with those shots. They turned out quite well. That's just a reminder to myself for when the pictures don't turn out nice: the camera is not my limiting factor.
