The top picture has great timing but there isn't a face to go along with the shot, still the timing is great on this picture, maybe move to one side and get her from the front while hitting.
2 is soft, and again there isn't a face. This is one of those shots where you move to manual if you want to get her or wait until your AF completely focuses (I use continuous mode when I shoot sports) then hit the shutter button the rest of the way.
3 another great shot, just no face.
4 is your mona lisa this is one great shot, great action, great focus. More of this.

First let me say job well done for your first time!
Chris gave you good critiques. The only thing I'll say is sometimes I love shots like #1 from behind. So I'll go with thinking the first and last one are very nice!
It's not blurry. It's bokeh.
