Your alignment is good - it looks like you're in line with the shot correctly from what can be seen in the video. If you can fully contract only your bicep and the stick consistently goes in a straight line through your follow through, it's fine.
I noticed your shoulder/elbow pops out on your follow through which can cause stick swerve. Minimizing your elbow drop might've helped that. This can also happen if you pull your stick through part of your stroke with your wrist or forearm instead of pushing it with the bicep, which imho is a very bad habit.
This is purely from an alignment standpoint. The quality of your stroke didn't really stand out to me one way or the other.
