I'm very curious to learn more about your fanfiction project. As a lifelong fan of both Greek mythology and Final Fantasy VII, the title you have chosen for your project (Dreams of Elysium) genuinely intrigues me.
As do the costume designs. I see aspects of Sephiroth mixed with Genesis in the design for Lucius (particularly in the colour version).
I would love to learn more about the project in general. If you want to, or when it is ready/complete, feel free to share the fanfiction itself with us too!
Love the sketches & artwork. Would love to see a link to the original artist(s) to check out more of their work, it looks amazing. Your Aerith dress you designed is very beautiful too, the artists did an amazing job framing it around her body, especially in the first image w/Sephiroth!
