I have very particular taste when it comes to graphic tops, which is how I came to own mostly plain hoodies and tees with few flairs. I also struggle to articulate what makes a design attractive, and rely primarily on serendipity to find new printed casual-wear.

The oversized fit also adds to its appeal (though I further upsized for extra length) and the price is extremely reasonable (now <$30 after 15% off).
This hoodie is available in a handful of designs; perhaps one of them will appeal to you:
