Angel Beats! may have ended, and everyone gone on to whatever lies ahead (Not giving spoilers!) but that doesn’t mean the end of Kanade vectors.
The scene from Ep11 where Otonashi pets/rubs Kanade on the head.
There is gradient shading on her hair (both light and dark) and face and Otonashi’s arm, but this time it was way easier to do (turning off the line and adjusting curves and nodes to make the fill cover the path below).
I haven’t decided wither to try and vector the background of the scene too.
