Reclaimed Fuji FP-100C Negative

I've recently learned that one can reclaim a scannable/ printable negative from Fuji FP 100C instant film.  This was very happy news for me, as I've been very sad since Polaroid Type 55 was discontinued, and a replacement/ comparable positive/ negative film would make me very happy.  I won't go into detail, but the process is explained here and here.   Here is the result of my first attempt, along with the instant print.  I'm not sure what I did wrong, but I think it has something to do with the emulsion.  The photo was  shot using a Pinhole 100 camera.

Reclaimed negative from Fuji FP-100C instant film.  I think my technique needs some work.
