starting with a basic one, you're using your major cd's a bit out of alignment. If you follow the guide for rotation, bloodshed and call of the wild align. purple/grey is what I would compare you against, which is the number one boss damage parse.
Bloodshed doesn't have to perfectly align if you're planning on using it AOE or the hybrid build in some capacity, but you're in Full ST. For true parse, it is a meme AoE situation where mythic guilds come in and cc the adds together like they would in higher difficulties.
Your opener does not match the guide, consider reviewing it and practicing it on dummies.
Small tips for the fight: Try to barbed shot while the boss is flying upwards during transitions to try and maintain frenzy
