I'm a big fan of the really angular slightly rough art style, the backgrounds are all beautiful and I really like the use of vibrant, simple, contrasting colors within the scenes. The animation is very well handled in how few frames were used in some places to really give it a unique weight in the timing.
As for the writing, I have to say it was hard at times to see where the jokes were, and when it was apparent the timing of the punchline felt off. I don't know if this is a personal preference, but I have to say that references to social media should function more as platform for the setting of the story or the joke being told, rather than being the joke itself. With the growth of social media over time the type of jokes that just use hashtags as punchlines, for example, have become so common place they feel cliched.
