@hookshy : general thoughts after having watched the latest video (having already bought some videos to senior producers) :
remember to keep a contrast in favor of the text or people won't read it (in that case, the blue color of the text is nice but the eye will be kept by all the black in the background)
remember to focus on the message :
why have you added the woman in the bus stop ?
why is the first question still on the screen after you had provided the solution ?
think about the music and the track's length : the way the video ends is too sharp => people remember the music and the video ends before the end of the master loop. Frustrating.
EDIT : and a word about the logo : is it the app's logo and why does it disappear so soon after you have provided the solution ?
But keep the good work on. Habits will come while the number of orders will increase (thinking of buying one too).
