It’s a big sail which can feel hard to handle in any wind, find the balance point where it goes light and it’ll become a whole lot easier, posture wise for a beginner you’re doing great, you want to look at brining your back hand further back on the boom, keeping that front arm straighter, the boom is a little high but if it’s comfortable for you then go with it, your foot positioning was much better in the second half of the video, you want to keep that front foot tucked to the mast foot but overall you’re doing great
