How do I add more yoga poses?

Gradually. Where is there pain? Where is there tension? What is your flexibility in each part of your body some will be more flexible than others; in turn some will be stiffer or painful. Explore your body from Head to Toe. Start by taking a deep breathe in and exhale. Gently lower your chin; don't overextended; respect your limits especially on your neck to avoid injury. Slowly roll your neck side to side breathing consistently. Roll your down your spine slowly until you touch your toes. Roll back up and gently twist to each side. Pay attention to your body and it will tell you where and what feels good. Twisting Stretches and Balancing Poses are my favorite because they are extremely effective and fun and challenging.
