First Impression of this photo was a feeling of gentleness.
Technically
First and Third pictures are well done, Good lighting and focus, the 2nd pictures is slighty blurred. Colors are just a tad flat, Maybe a little more contrast.
Composition.. Set up is nice and the pictures flow well
Meets Challenge
Yes
Final Thoughts.
This a nice picture and well done for a first time model. She seems relaxed.
The colors are a bit flat. I look for bright whites and the parts that should be dark, need to be really dark.. A touch of curves would have made a big difference or playing with the brightness & contrast. IMHO
