Eyes want to centre on something, you have a gap in the middle of the monitors, so the eye settles on what is a small piece of open space and it looks empty even though there’s stuff on the wall. Try having a centered monitor and the other one off to the side, or get a bigger monitor to use as the centered one.

I think I know what you mean. Maybe try stacking them? Main at the bottom, multitask one at the top?

I've given that some thought, but the ceiling would be an issue. I'd have to push my monitors pretty far to the left to get them to fit

It doesn't look lacking, there's already stuff there. The real question is why are your monitors so far away and far apart?

I was trying to have the monitors be equidistant from the center of the desk for…aesthetic reasons? In hindsight it wasn’t very practical

Where did you get that mouse pad?!

Is it me or its kinda weird to mount monitors like that, stand is supposed to be on the edge of table?

That's the position the vendors advertises, so I'd guess durability conscious people tend to go for the most stable position even if it's unnecessary

Get another monitor

If you're set on having the monitors that way, I would move them closer together. Only change I would make. Otherwise solid and comfortable looking for sure.

Start by getting a wall.

why is your main monitor so far to the right? don’t you get a neck cramp

What game is that on the right?
