Stuart,
I like the colours. Interactions between parent and child is always nice. I would be tempted to tone down the whites a bit. Do you routinely shoot at ISO 100?
Thanks Sabya. With regards to the ISO, I normally shoot at 400. In this case, these guys were quite far, so by reducing the ISO, and knowing I was going to have to do a large crop to make something of this, I reduced the ISO, so as not to bring out any more noise than necessary.
