Assuming you’re asking in earnest:

On a surface level, the banal averageness of features. There is no artist’s style — it’s just drawn in form of the “generic web comic” genre.

On a closer level, there are inconsistencies with background details that wouldn’t occur with an actual artist’s work. If somebody was manually drawing the background digitally, they would likely copy and paste the assets to both be consistent and to work efficiently (without a compromise to the work itself). The door and shelf of bottles behind the Helium change between frames, for example. If an artist were drawing this with physical pen and paper, they would care enough to meticulously recreate the bottles between frames if they were even going to include them with that much detail at all.

The text itself is also revealing. Not only is it inconsistent in size, boldness, and centering (ex. from one He to another), but the words spoken by the bartender are running out of space in the speechbubble. Artists can make mistakes like this in their publications, but consistently making errors that a quick lookover would catch shows that the “creator” of the content just wants it made, rather than it made well.
