Thanks for sharing your work! I wish my first portraits had been as good as these! Good job!
The first thing I like about these photos is their sense of calm and quietness - these two women appear comfortable in front of your camera and not pretending to smile for the camera. You have directed them to show a genuine and calm demeanor that I find very appealing. I like the classic appeal of the third image with the red serving the function of a frame within the frame and directing the viewer to the woman's face. On the center photo, the color palette works really well, with her hair tones and the background unifying to create a harmonious olive color to match her amazing eyes. I also like how you've separated her from the background with a back light. And the shallow focus seems to work well too. Very nicely done. The second and third are my favorites for the classic simplicity and the expression of the model.
The first image has some unessential elements - her watch or bracelet, the stuff on the bottom left, the curved lines on the background, the pose of her hand and how her hair moves up, the rim light - these are details that don't add to the portrait, and if they don't add, they take away. Watch rim lights as they can make a fine portrait look contrived and more about the photographer than the person being photographed; let the light tell the story about the person in front of the camera, but the light should rarely be the story itself (there are exceptions, of course)
Great start and looking forward to seeing more!
