You need to join a creative writing class and take your chapters for the teacher and students to read and critique. That is called a writing workshop. If your characters are not believable, they'll say so and give you ideas on how to fix them. If you can't join a class, look for writing workshops in your area. There are writers who meet in coffee shops to discuss each other's works.
