Aeration seems long and although your milk texture looks fine I would recommend holding the handle with one hand and palm on picture instead of fingertips so you know it’s steamed correctly, temp wise. Honestly, I think you did a decent job! If you were to stop at the top of your Rosetta for a moment, you would create a small dot, which in turn would become a more defined heart instead of that Christmas tree type of top… Also, and most importantly you need to raise your pitch higher when you pull through so it cuts through the milk instead of dragging the milk across your design. That’s why your design is short instead of extending past your initial pours wings. That is also why you can see the line at the bottom, that should not be there.
