For me, for this snippet, the main element that needs fixing is the camera movement.
It feels like an old game cinematic.
It stopped too suddenly in the first scene and the second was too static.
Possible solutions for the first scene:
Use ease-out/deceleration movement.
You can cut before the camera comes to a complete halt. But it should be on the move too slowly to to so.
Possible solutions for the second scene:
Use slow-zooming movement towards the object.
Use targeting to keep the object on the center of the view.
Use both of the above.
So the main problem (as I see it) is cinematographic/directorial
I suggest you study all of the videos in this amazing channel but start from this video about camera movement and this video about camera angle and built your knowledge from there.
The second problem is compositional.
The floating particles and cross are all in front of the sword shuttering any perspective or depth of the sword in the center of the scene.
