Messy: How to Be Creative and Resilient in a Tidy-Minded World aka restriction is freedom when painting sheep or

I've just started reading the book "Messy: How to Be Creative and Resilient in a Tidy-Minded World" - anyone who has shared an office with me will testify that my desk usually acts as a visual advertisement for the title of this book! :-) - only got through the intro and chapter 1of the book so far but I am really enjoying it. Much of the beginning centres on a concert pianist who produces an incredible performance despite having a defective piano. The point of the story being that sometimes difficult circumstances can help us to think outside the box and create things that we otherwise wouldn't have. 
I actually use this technique when I paint from time to time. In the example below, I restricted myself to using just one brush and ended up creating a sheep painting that has a look that's truly unique compared to others in my portfolio. Check out "The Golden Fleece" in more detail here.

Cow Painting - Chit Chat

"You know what Martha? I heard that Beatrice in the next field is very impulsive, she's like a bull at a gate with everything she does!" This is 'Chit Chat' A couple of cows having a chat in a field in Branscombe in Devon United Kingdom. See the painting / buy a print etc here.

Cow Painting - Guardians of the Valley

'Guardians of the Valley' Two cows, horns still intact, lying in the misty twilight of a Devon sky while surrounded by green and yellow fields overlooking a valley lined with hedgerows. See the painting in more detail here.

Cow Painting - The Courage of Youth

"The Courage of Youth" - This young cow was found in a field north of Exeter in Devon. In this acrylic painting I've deliberately used non-realistic colors but at the same time endeavored to keep the hues harmonious so that they are striking but not jarring. The "blue lighting" has become something of a signature in my work and can be seen in several ofmy animal and figure paintings. You can see the painting in more detail here
