Hi Katie, welcome to EPZ!
This is a gorgeous initial upload, I love the way you've caught the mum and child!
I've taken it into Photoshop Elements 9 and made few small tweaks (I hope you think I've improved it!)
I took it into 'Enhance' > Adjust Lighting > Levels.
Then I adjusted the midtones and highlights.
I straightened the horizon slightly and gave it a little crop to bring the mother and child off center.
Because I adjusted the lighting the sky was a little noisy, so I took it into 'Filter' > Despeckle & Reduce Noise
There was a very slight blue cast, so I've removed that.
A resize and quick sharpen, and here it is!
Edit: Mmmm. I may have cropped a little too much, a little pixelated in places.
It was a gorgeous image to play with, thank you!
