It's not really my thing, but having looked at a couple of your videos, I would suggest trying to increase the depth of field, which is done by stopping down the lens. On auto lenses this is achieved by increasing the light levels.
The other thing that might help is to watch some of the YouTube videos on editing and creating scenes. The video with the lunch break queue is an example of one where the concept is a good one, but it feels like the comic effect could be made sharper. It felt quite planar (everything ranged across the frame giving a flat effect) and would be nice to have e.g. shots along the length of the queue. This would enable an extra gag of people getting impatient, perhaps popping out sideways to stare at what is going on.
Hope this little bit helps!
