Clearly a lot of effort and love went into this project. I enjoyed the animation, it fit nicely with the tone and style you were going for. I also thought that the character designs were distinctive and represented the characters well.
My main criticism for this animation is that the writing isn't that strong. The pacing of the story is slow and we spend the first four minutes without the story progressing at all. I understand that you were aiming for a "clerks"-esque sort of intro where we get to know the characters but I don't think it should be at the sacrifice of telling the story. It made it less like a complete story and more like a series of tangentially related sketches.
That being said, I enjoyed the animation style but I think that the writing is the major issue with this. If you were to strengthen up the writing/jokes I could definitely see this series gaining traction online.
Good luck and I look forward to seeing future videos.
