Are you unhappy with something in particular? Logs are looking kinda okayish...
You don't have advanced logging active, so we can't say anything about mana management. You are still using Trail of Light, which gets less and less popular these days, but still got longer times without any castings in like every fight (e.g. 20 seconds without any cast).
Try spending more mana if available, Prayer of Healing is a nice way to throw it in the raid. Once you come to the point where mana gets short, switch to Enlightenment. It won't really help with HPS, but once you are bored in the raid, do damage to the boss. Avoid those 20 seconds of doing nothing.
