To me the effect of bounced flash looks nice with soft skin tones.....the light on her right cheek give a good modelling effect, as reflected by bouncing....You can achieve good effect bouncing off side walls(white),placing some white thing to reflect back,if the walls of some colour...reflecting from ceiling, a reflector nearby your camera,flash head turned to it. Use an umbrella with stand, as your choice indoors and outdoors...direct flash kills the natural effect of light, as harsh one.....However outdoors, u can use direct flash shooting against light to fill in shadows in portraits....The catchlight in eyes will help bring out the life in the face.
