Its pretty empty with almost no lighting even if thats intentional the way the lighting is set up is quite poor, probably not inviting to newer players
Things feels to far away, it feels like too much work to get onto the other side of the room. Lobbies should be more inviting and possibly create suspense but not set out an eerie mood straight from the get go.
How many players are allowed in the lobby? If the amount allows it, maybe make the size of the lobby smaller to make up for the big amount of empty space.
If you don’t mind me asking, how does your lobby work with your game? Does your lobby contribute to anything functionally in your game (like in story games where you can interact with an invisible wall in the lobby that puts you inside the teleporter) or is the lobby just for people to hang out and wait for friends to play the game and they would join via the user interfaces.
In my opinion, I think you don’t need to make your lobby too spacious then because it doesn’t seem like the players will be doing much in the lobby but just waiting for friends or talking to others. If you wanted to, you can spawn 40 rigs in the room and place them in a grid to see how much space 40 players would take up and work with that. The scene without players looks pretty empty but maybe with 40 rigs to imagine how it looks, it might not look as empty as you thought.
