The design for Thornhill's apparel collection for their new album and track "Arkangel" embodies the thematic essence of duality inspired by the song's narrative. The central concept revolves around the tension between two lovers, depicted metaphorically through an angel and devil motif.

The apparel designs feature striking graphics that juxtapose angelic and demonic/vampiric imagery, creating a sense of contrast and intrigue. The angelic elements exude purity, with ethereal wings and imagery taken from the music video, while the demonic elements convey a sense of darkness and intensity, with fiery accents and sinister motifs playing off the bands inspiration from Buffy the Vampire Slayer.

Typography is utilized to further reinforce the duality theme, with textural contrasts and stylized lettering adding depth and dimension to the designs. A simple color palette was used enhancing the visual impact of the apparel.

Overall, the design captures the complex narrative of "Arkangel" while providing fans with wearable art that reflects the song's thematic depth and emotional intensity.
