Empty Heart Latte Art Tutorial (aka Hollow Heart)

The only tutorial video I've seen for this is by coffeefusion and he had some trouble with it. I recently documented my learning process and decided to contribute to the community.
This is from my instagram @homecoffeegrind

Any more hints?
I have tried many times but still failed to make a hollow heart.
