A bit like London buses. Here comes another sketch!

We're planning a holiday in The Highlands and inevitably, when looking at some of the photos online, I came across a number of pictures of the iconic Highland Coo. So, I decided to have a quick go at sketching one. Here it is. If I get a bit of time, I'll be returning to this subject and maybe experimenting with acrylic to get a finer finish to the hair. Enjoy!
