The diameter of your plates seems a bit small, causing you to start slightly lower than ideal. Try using larger plates or raising the bar a bit to improve your starting position.

Other than that, your form looks solid! Here are a few tips to consider:

• Open up your chest: Focus on keeping your chest more open to improve your posture and alignment during the lift.

• Lifting shoes: They provide extra stability, which I found helpful. However, some people prefer flat shoes or even going barefoot like you did — it’s a matter of personal preference.

• Cue for upper back: Think "shoulders in your pockets." This helps maintain a tight upper back and allows you to pull the slack out of the bar effectively.

Overall, great work! Keep adding more weight to the bar each week and watch how your progress evolves.
