I write and make art for multiple fandoms. You can find me mostly on AO3 as well:


  1. I love how vibrant your art is, and your cast images just made me so happy. I adored them.

  2. The black-and-white banner is gorgeous!

  3. I love the art! It so fits the story and I appreciate all of the hardwork on this. Each piece is really well don, and the black and white with Tony and Phillip is my fave. Love the bright colors on Jack/Nathan. Thank you so much.

  4. Nice art! I’m a math major, so I kind of love the background equations and the chapter headers. Love!
