I'll chime in here because we're shooting something similar this year, if I can find the perfect prop car. I'm a sucker for "Odd Couple" duos bumbling through scenery while bickering all the way. Volleys of witty jabs and one-liners mixed with dime store philosophical rants tend to put a smile on my face, assuming the actors know their craft and the writing is polished. THE TRIP
http://www.imdb.com/title/tt1740047/ with Steve Coogan and Rob Brydon managed to pull this off in its own way.
That said, I didn't get all the way through your movie. Why? The audio quality was dismal, the dialog seemed uninspired, and the shot compositions didn't grab me. Sorry man.
It's your first short film, so no one is expecting a masterpiece and I won't fault you for putting your efforts out there. My first films weren't anything to write home about. Come to think of it they were pretty terrible!
The good thing is: you got actors together, shot the shots, cut it up, and put in on YouTube for the world to see. Now the game is to do that over and over and over for the next few years to learn your craft, find your voice, and tell great stories.
Keep writing and shooting!
