Here's my try at editing. Below are some suggestions.
Face you subject looking into the frame, not out of it.
Don't center your subject in the frame (you didn't -good job, but her eyes are dead center. Put them 1/3 of the way from the top. Google rule of thirds and let it help be your guide. ( i cropped to put her eyes higher)
Not sure what camera or exposure you used, but the pic is dark. You could fix this by bumping your ISO up higher and allowing you shutter to stay open longer.
Use your white balance. Your pic was yellow because the ambient light in the room was either a household lamp or the Christmas tree lights. By switching your WB setting to tungsten you could have balanced the yellow tone out.
Try to have you subject looking into a light source. A window is a great source of natural light. Look for catch lights in her eyes. An eye with no catch lights (light reflection dots) look dead and lifeless.
One more thing, have your subject turn their head towards you, not their eyes. Body slight angle away from you, shoulders uneven and eyes toward you. And focus the camera on the eyes. Everything else can be out of focus, if the eyes are in focus you've still got a good pic.
Keep trying. With practice you'll get better and better!
