It is a rather good clip for a 1st timer! Love the part where you pause the music to let the HP's auto-reply come in. Fits the music perfect. Your flashbacks are also nice (altho a little too confusing by jumping everywhere). Makes the viewer think instead of digesting the video blindly.
I feel that there is a story, just that it is edited into an MTV style. The only confusing part was why the girl went for the other guy. If you had the couple quarrelling in the car in the 1st scene, it will make more sense.
Since there is no dialogue, your cinematography and editing are rather good in being able to tell the story well. E.g. the use of color difference to indicate time difference, flying of papers to indicate accident, etc. I enjoyed your clip.
One fault I find bothering me are the words on the girl's PC.... "happiness guy". It should be "happiest guy" lah...
Haha! Keep it up. Have fun!
