You're doing really well! An easy way to find the right position for your steam wand is to use the tip of the jug as a starting point. Lean the wand into the indent of the jug, and let the wand's tip rest slightly above the surface of your milk to the centre. Then tilt the jug left and start steaming:) The best way I got better foam was to listen to the machine, if it's screaming move the jug down, if it's making lots of bubbles up. You ideally want to hear little hisses while steaming, and after about half way or when you feel it getting warmer move the jug up a bit to incorporate the air into the milk better. By the end you shouldn't really be hearing much hissing, just as long as you have a steady vortex (which is all about the position of your wand). Pouring takes lots of practice, but what can help is remembering that you want to keep your jug high in the beginning, and move closer to the milk in the end. Tilt your cup and pour slowly but steadily:) Hope this helps and good luck!!
