With the various Bears being posted, here is another, albeit one that has been posted a while back and illustrates how quickly you can loose DoF, however the eyes are sharp, but with this I wanted to ensure you just had the head and where everything else just disappears and so all you have are the eyes & nose (albeit OOF) of this awesome subject. Just keeping things simple for this B/W conversion, however I will post the colour too.
Thanks to those who both viewed and more importantly, commented.
