Well, you're showing us a very small slice of the room, with no walls where art, etc., might go. II'd try to align the table and light better, and lower the light about 12-18 inches. Otherwise, I'd try to take some colors from your rug and reflect them in art and/or decorations around the room.

• Curtains/blinds
• An upgraded light fixture, lowered
• A bit smaller dining table that fits the space better and is pulled away from the wall so it does not looked cramped. Or use a bench along the window side and add a table and 2 chairs in front of it
• Pull the rug away from the wall as it looks like it is up in the corner causing it to ride up the wall a bit
• Decorative bowl on table
• • Chair pads that match each other, or all different, and less chairs
• Clock or art on wall (above knife block)

First thing I'd do is place the table and rug both directly centered under the light, as mentioned already. Next, I'd remove the silk plants from above the cabinets. That's about all I can suggest so far with the current pics.
