I agree...it's too much.
The trick with skin smoothing is to keep it subtle...well that's usually what you want to see. Sometimes the 'plastic' look is what you are going for. Use a lower opacity brush and or lower the opacity of the blur layer.
The very best retouchers will smooth out the skin but keep some of the natural texture...which is much more believable...but it's a more advanced technique.
Also, when you are removing the blemishes and what not...it would have also been a good idea to remove the glare on her face. Of course, it would be better to start with a photo that was lit better...in this one the light (flash) is too direct and maybe too strong.
You are off to a good start...practice is the key so keep it up.
