Make sure you are spreading the floor with your feet by setting your stance and then twisting your entire leg outward. Foot, knee, hip. This will engage your hips and glutes better giving you a solid base to press from.
Try to get your wrists a bit more inline with your elbow, making them straight.
Really focus on pushing your knees out not just on the way down, but on the way back up.
Lastly think about driving those elbows down, you're not in a horrible position but once the weight starts getting heavier you will probably start falling forward more readily with your elbow positioning.
Just keep dialing it in. Good work.
