Hi, I'm Helena! I'm a communication designer, game developer, illustrator, and award-nominated 3D artist based in Copenhagen. I craft visuals for interactive media, games, creative technology, and immersive experiences. Previously, I taught game-related classes and ran 3D modelling courses at a university level. You might have seen my work exhibited at the Rondo Sztuki Gallery, Porto Design Biennale, and more. I love improving the player's journey by crafting sensory-rich visuals, making every moment of play worthwhile! Interested in chatting? Discussing typefaces, game communities, and marketing over a cup of mint tea and croissants? Feel free to reach out :)
