I know this is a hard subject. I had this experience myself. When my husband and I got control of the shock ( you never totally get over it ), we wanted to try again. Now we have 4 kids. Anyhow, If it were me I would finish it and put it away. They most likely will try again someday and then it would be the perfect gift. Meanwhile just let them know you are there if needed. Good luck
You should be the prez of the Hugh Laurie fan club You did a great job. I'm a fan myself. I think he would be flattered to see it. Keep creating. I know from experience an artist is her own worst cridic.
