I quite like the second image. To get a really good action shot you’d (at least I would) normally take a good few shots. The second shot seems pretty well composed but there are a couple of things I’d try to do differently. I’d use a long lens and/or separate the model a little more from the foliage to create depth of field. The focus also seems a teeny bit off to me.
The first shot seems like you’ve underexposed significantly and then tried to rescue it on selected areas and applied saturation, it seems too much to me. You might want to try to bring the whole image back a little in camera raw and then work less on the areas you want to give more emphasis to.
it looks a little like the shutter speed was too high in the first image?
You need to use high speed sync if you’re using flash… :)
Second image is lovely
