Lovely model.
While you have created some nice visual lines with the posing, the are a few things of note IMO that you may not have considered.
The hand position in #1 is much better geared for the female model. #2 has the back of the hand mostly towards the camera which make them look larger than they surely are. A more feminie position is to have them in profile or closely. Meaning that the thinner edge of the hand is favorable. However, in both images she seems to receed into shyness by having a closed posture.
The tilt of the shoulders in #1 is spot on. This pose creates a much more dynamic visual than the typical "football shoulders" (square to the lens).
In a tight crop (#1), don't be afraid an even closer crop by having the eyes in one of the power positions of the ROT guidelines. This may mean to have the top of the head out of the frame. I do not have an issue with this type of framing if it looks purposeful. Experience will be your guide.
If you have a chance to shoot something similar as in #2, try lowering your camera position slightly. Even with her smile, this seems to be a domineering position. I would also suggest to have her open her right shoulder to have a 30-45° to the lens axis. Then place her hand (with the back edge towards the camera) on mid-thigh. Another little trick is to have her place her weight onto her hip rather than sitting flat on her bottom.
Both images look as if lighting was mainly from the built-in flash. Rather flat without any modeling (shadows) and #2 suffers from the camera rotated into portrait position and the flash throwing a shadow against the background camera right. Move the model further from the background to combat this. Also, avoid backgrounds that will bisect your subject (baseboard).
You've done well, just a few things that I see. YMMV.
Thanks for sharing.
