Little C&C please

[Fotografer]

I took these on the weekend, like them very much and feel it is the best quality wise I have taken so far. There was this nice shady section with the sun shining in the back ground. Just looking for comments on how I did over all with lighting, composure and setting choices. I was trying different settings to see what I could come up with.</p>
