Zendala dare 28 and colour scheme

I liked this zendala design so much I did another one!! For this one I used the split comp colours blue, purple and orange-yellow. I didn't have an orange pen so used red then coloured over with yellow to get a similar effect. In the design process I found myself inventing a tangle. It sort of 'popped up' by itself! I also did a line around each shape inside it as an experiment and quite like the result. I couldn't stop looking at it afterwards. Is that crazy or what?
