If you don't like it and can afford it: leave it to a charity organization. It's a beautiful work (not my taste either :), I don't do people) And it would be a pity to lay so much energy on something you don't like, start something new. Good luck!
You have my admiration for continuing with something you don't like. Can you pass it on to someone else and find something that will bring you some joy when it is finished?
