I agree with the C-tables.

Not sure if I understand, aren’t those tall like a side table?

I would move them slightly more apart and only put a coffee table in front of the sofa. A long narrow coffee table.
The chaise sofa does not need a coffee table in front of it.

Yes, they are taller than a coffee table. But your set doesn't room for a coffee table. You would always be bumping your knees. Can you post a picture of the entire room?

With "C" tables, you'll be able to center the chaise sofa in the window. That will help balance the two better. Let's work on your hanging items too.

Maybe a small ottoman or pouf would work. It could do double duty as a place for drinks (with a tray), or as a footstool. If this is an area with a TV, it’s nice to have a place for everone to put their feet up.

Perhaps adding an area rug would add that wow you’re looking for. Just picked this one based on the one blue pillow.
Then as stated above, just add a small footstool with a tray on it.

This rattan footstool is 20” diameter which could possibly work.

Is there enough space to put sofa where loveseat is and have loveseat across from it? Window spot would be open. I would look at adding a rug then table.

Where is the TV? I think there has to be a better furnishings arrangement for this room.

The furniture is facing the tv. On the other side of the chaise part of the sofa is a large fireplace so the TV cannot go there. decoenthusiast, you don’t care for my hanging items?

It might be a good idea to look into small ottomans or a small round coffee table. Below are some ideas from designs we have completed for our clients:
