Struggling with muscle wire

After placing the sheet of plastic with muscle wire on the mirror I made connections out of copper tape, soldering, and jumper wires that ran all the way down the mirror and over the edge to the Squarewear on the back. I am not sure if there was something wrong with the connections or if it was something else. At that point I couldn’t know because my battery died and I wasn’t able to verify what the problem was!
