Stop analysising, the need to "get to taste or smell' indicates that you are working according to rules. The only rule is to talk out loud and include all your senses. It doesn't mean that you have to work down a list in your description it means follow what your internal eyes ears tactile and emotional senses playing at while you describe. Whatever is important will try to take over the image stream so follow that. If the scene changes it means decribe the new scene now. If it creates an emotional reaction you describe that.
