I had to improvise because the bright owl did not post a dare challenge this week. Fortunately there was a fast solution to this problem because I only joined in the fray half-way along, so there are lots of zendalas I have not attempted.
The first one I downloaded was dare 13, which proved to be quite a task! Though I started on the lines, I soon got distracted, removed the outside lines in favour of organic patterns and here are 2 coloured versions! For comparison, I've included the template.
