I dunno what the purpose/background of this work is (fun/school/work/etc.) so i just take it as it comes off. First things first, i like it. The effects are good, camera angles are good and the lighting is good, too. What, in my opinion, is a minus though, is the model/actress. It's not acted/performed well.. It just looks too wild and like she was running out of ideas of what crazy things to do (still, don't know the background of the work). Also, some scenes cut/break the tension/dynamic the others created - namely the ones where she looks directly down into the camera while smiling (again, dunno the purpose). Other than that it's a great video and a great piece of work. Like the scenery/location, too.
I hope criticism is appreciated but on the other hand You didn't exclude it.

P.S. i am not a professional at this but more an amateur and my opinion is solely subjective nature.
