Mirra walking cycle (with video)

I did a walking cycle with Mirra for test her rig, however I couldn't figure out a good background. So I just say "What if I just integrate her with a recorded video?" So I did a record on the street trying to imagine her speed and position. Then got the 3d camera with after effects. I learned quite a few things in the process.
After that took 4 days of non-stop rendering (in a Phenom II X3 with an RX 580, rendered in Blender, Cycles) and here is the result.
And why she is carrying that Axe? I was toying with the idea of making her grab an object with her two thumb hands. Also I wanted to use that axe I created last year in some kind of animation, So, it just seemed logical.
