That was really charming, and I enjoy the dynamic between the two characters. I like the artstyle as well, the designs are unique and have that classic internet animation whimsy. Also the house was pretty well drawn, and the colors of everything were great. I also like the setting, just driving on a day to hang out with your friend, just the small, good moments in everyday life.
If I may make a suggestion, would you possibly add a bit more distinguishing factors between the two main characters? Maybe one is taller or has a thinner head, and also a bit of the animation (particularly the waving silhouette at the beginning) could have used some more frames.
Overall, I liked it quite well, and I look forward to watching the rest of this series.
