Welcome to the boards.
She's a cutie. The first one looks like she might have been approaching the minimum focusing distance on your camera. Part of her face looks in sharper focus than the other. It could also be a shutter speed problem (too slow a shutter speed and you could have motion blur), or depth of field problem (too side an aperture and you don't get enough depth of field), but I don't know what your shooting settings were to know for certain.
The second shot is a really tough lighting situation. I like the composition (her out of the center of the frame on the right side). The bright window light hitting a portion of her face is a problem, though. That super bright stripe comes out overexposed, while the rest gets a little underexposed as the camera tries to deal with the very uneven lighting that creates.
Keep shooting, keep practicing, and keep posting!
