Hi, Chi,
Pretty shots.
On the technical front, I think No. 2 suffered from blowout of the highlights on the face. (If course such is almost unavoidable - and not really problematical - on the window.) It gives the delivered image a somewhat "amateur" appearance.
On No. 3, I personally would like to see more contrast. Perhaps such was not available from the original image, again perhaps afflicted by blowout.
You may need to reflect on your overall practices with regard to metering and exposure.
I don't know what kind of camera you used (there was no Exif metadata in the images you posted). Many photographers working in situations such as this prefer to take the raw output, which is often more forgiving of non-ideal exposure, and we may well be able to compensate for such during raw development.
Thanks so much for letting us see your work.
Best regards,
Doug
