SYMMETRIC MORNING GLORY

I really love and, for sure, will adopt this symmetric pattern making method.
For this course project, I chose to play (simplified) with the morning glory flower shape.
I am french and flower names in english are just so poetic ! "morning glory", "Forget me not" :-)
This is my second try at this symmetric method. With the first one (here: https://www.instagram.com/p/C6s7AXYNnKh/ )... I did not make it properly symmetric inside the diamond. it was Ok but did not look quite like the demonstration into the course.
Thanks
