Hi Jemima,
You’ve got two good compositions there, especially the second. The second feels a lot more personal than the first (though both are well done); I can see the person, rather than just their hands. I can feel that they are sitting, perhaps meditatively quiet, reading.
Also, your focus in both shots is tack-sharp, with a gorgeous background blur.
A comment would be that your white balance (the balance between yellow-blue and pink-green) is shifted a lot towards the blue, and a tad towards the green. That tends to make a picture look “cold” and a bit unwelcoming. This is an adjustment you’ll have to do on the computer in post-processing. Just as an example, I’ve attached a “warmed-up” version of your picture.
