I'm not expert but I can tell the style of content you're going for, and the Hitman down under video made me chuckle. However the ending was way too long like I was expecting more but it never came. I'm not sure what exactly it is about your videos that aren't hitting quite right but something is missing. I'd take a look at "SovietWomble"'s videos as he has a similar, much more refined style of editing such videos.
Agreed. 3 second content in a 16 second video? Also, why are you advertising your YT channel when you haven't uploaded in over a month?
What's the joke in this video? In fact, what's the joke in all your videos? Placing music over a 3 seconds of gameplay is just what it sounds like: Putting music over 3 seconds of gameplay. If you are trying to go for dry humor, take some inspiration from this guy: Otherwise, Keep doing whatever the hell you are doing but it wont get you views and subscribers.
