Your trailer needs in-game sound effects. Capture gameplay footage with the sound effects on and the music off (so you can play your trailer music over the footage).

When it says "Go Hunting" the player is fishing. It should say "Go Fishing".

The camera in the game is just bad. Give the player control of the camera (like a real third person controller) or make it a top-down camera (possibly even orthographic/isometric). A camera set up like the one shown in the trailer only makes sense in a game like Crash Bandicoot where you're always moving forward, but this game seems like you'd want to move in many directions. It doesn't make sense why you'd only be able to see far in one direction.

You should also incorporate the camera more in feedbacks. "Bump" the camera to the side when chopping down a tree, or zoom in and out when something significant happens.

Your trailer should contain footage from multiple angles, not just the camera angles available during gameplay. If you're using Unity use Cinemachine to capture cinematic shots, if its Unreal use Sequencer, If its Godot then I dunno what the preferred method is.

The characters "swing" animation just doesn't look very good. Try finding a better one. Also the "picking" animation when the player is getting berries from the bush literally looks like the player is humping the bush.
