Create a T-shirt design featuring the Marauders—James Potter

Create a T-shirt design featuring the Marauders—James Potter, Sirius Black, Remus Lupin, and Peter Pettigrew—in a powerful line-up pose. Show them in battle-ready stances, with wands drawn, surrounded by swirling magical energy. Use a fiery color palette with bold reds, oranges, and golds, and incorporate the words "We Solemnly Swear We Are Up to No Good" in an edgy, graffiti-style font.
