In the Netherlands we call these clouds "sheepclouds" probably cause there is a similarity somewhere..since you are a kiwi and live in sheepcountry numero uno i thought this photo to be very appropriate for you!!
Wow, look at how uniform they look! They're just like cotton balls, all looking straight down on you - smiling. Personification aside, I see 3 different layers of contrast here! Good one, Aaron!
Are you sure those clouds don't owe their existence to the craftmanship of someone proficient in Photoshop? I have never thought such a cloud formation would be possible. Awesome shot!
