A nice start ! My favorite is the last one. But, If i may, why cut the arm ? There should be more dead space on the right of the picture. For the first one, it took me some time to figure out what i was looking at, the way the model was place. For the second one, I understand what tou wanted to do but the highlights a really too much overexpose and too large on her lap. The third one is almost perfect, except the frame is too tight. take 2 minutes in Photoshop to remove the cloth tag.
