As has been said, this is really difficult from a couple of photos, but here are some tips:
1. You definitely need to work on balance/stance. Your legs are locked out / straight in two of the three photos, which means you have your weight too far on the back of your ski. Think hard in your next ski about moving your weight forward not by squatting, but by rotating your ankle to move that front knee over your left foot. A good friend often says, “If you feel like you are putting 100% of your weight on your front foot you’re probably only really putting it at 50/50.” It’s not natural.
2. Keep your hands low. I would appear that you have the handle a long way from your body. Think about keeping the handle down at your hips, especially when you are in that acceleration phase. Even on your pullout - keep that handle low.
3. Be patient in the turn. This might be the easiest or most obvious thing that I see in these photos: You have both hands on the handle way too early in both turns. Release (keeping the handle low), reach forward, wait for the ski to completely come under the rope and then grab and go.
There are a couple of episodes of Spray Makers that would be great for you to have a listen:

And finally - you are doing great! Keep it up and have fun!
