its a good short and good attempt at fight choreography.
My criticisms would be:
1. Lighting - when the car is outside the room we can see the light in the window it's really off putting for me, I would have placed it elsewhere or masked over it, the best idea would have been to turn it into a practical to blend into the scene.
When she's on the bed looking out the window the light coming through doesn't feel natural and looks placed.
2. The fighting - it's a good attempt, probably better than what I could do, but my thoughts on it anyway, cuts are a bit weird, hits weren't believable, when she strangled him both times there was no strain so we knew it was soft, when she hits him with one hand on his back he flops like Brock Lesnar just hit him.
3. Pacing after every hit - it just didn't feel right, but it's more of a preference thing, Iv grown accustomed to seeing 3-4 hits or more then a cut to make it more believable than a USA style of cut cut hit cut hit cut etc again just preference.
4. The look - aside from the lighting placement issues, I dig the look.
Overall it's good but just those little points addressed and it's a really good fight scene.
5. Story - I like the fact she has to take off the tracker and not just end with him on the bed, you gave her purpose which some people forget to do.
