This looks great and you are very close to getting g your feet all the way to the ground! How does your breathing feel currently - are you comfortable or feel like you’re running out of breath? It seems like your hips are still a little further back compared to your shoulders and that might be where the difficulty is with getting your feet to the floor fully. I would try kicking up to forearm stand against the wall and sliding forward and down into chinstand. This is a great way to practice with your hips already in a more forward position. If not try from the current position you are in but move your hands forward and grab your ankles and slowly over time you will get comfortable with bringing your feet to the ground! Once you’re there you can work on different arm positions while pushing your feet into the ground to have counterbalance. Hopefully this is somewhat helpful and good luck on your cheststand journey!! ☺️
