Disappointed

2 weeks ago all the midwives and MSW in our community team went out for the evening to a glass fusion course. Most of us had done it plenty of times, including myself. My piece evolved initially bcz my first cut instead of cutting it into 2 equal halves, with which I was going to do 2 separate pictures, it went wonky! And an idea occured thinking I could hang one above the other to create one picture overall from 2 pieces.
It went quite well, but upon picking it up today I am rather disappointed. There is a large blackened area below the middle figure, including a bubble. Also the spearhead has gone wrong, with one of the lines dropping and moving.
I don't know whether to hide it in the back of a cupboard or hang it on the wall.
