Strange Geometry, 2013.
I had the honour of being commissioned by Tsukiori to illustrate a scene from their magnificent magnum opus of a fic, Strange Geometry, and was given free hands to choose any scene I wanted. I went with a dream sequence between Daniel and Rosyth. This remains my favourite commission piece I've ever done, and one of my favourite fics of all time from any fandom. Go read if you haven't, you can find it on AO3 and FF.net!
