Milk Frothing. What am I doing wrong? Self-learning barista

Hello everyone!

I recently started learning about espresso and overall coffee making. I’m having trouble with milk frothing. I’m using Silk Almond Milk Sugar free and the wand is from the Breville Barista Express.

My problem is that the foam gets too thick and it doesn’t flow down with the milk when pouring, ending with a big foam on top. How can I fix this issue?

Thank you for all the tips! 🙂

(I’m aware the “art” looks silly please bear with me haha)
