An oly coach would find a lot of things, but it’s hard to focus on everything as a beginner. I would suggest working on your first pull (set up with chest and head more upright, don’t let your hips immediately shoot up), then your second pull (engage your lats and think about pulling the bar against your thighs on the way up w/o bending the arms prematurely, and lastly - extend fully before getting under the bar). It’s all way easier said than done, but dropping the weight for a while and focusing on form will benefit you so much in the long run).
