At the moment I have an antique brown tv stand and the matching light wood coffee table end tables but I know I need to go darker. It took me forever to find some artwork that would work with the couch. Hoping that at least looks good!

Have you considered painting them? The end table might look great in that dark burgundy color from your accent pillow.
If the room has too much wood, you might consider a glass or glass and wood coffee table to lighten up the look.

I have actually not considered painting them yet. The current coffee table is square shaped and I was considering something a little less wide and more long.

At first I was having trouble figuring out what to hang above the sectional and actually found a great price on that artwork that has all the same colors as the throw pillows of the couch and a little warm orange that's in the accent pillows

Not really, you need more color, change some pillows to solid orange, and add some smoky gray you can even add touches of yellow or red. Get some odd color bottles with different shapes in orange or red place on table, add throw red in color under your pillow center of sofa...besides your picture add two odd colors frames....

I would agree changing the square table out for a longer rectangular table

Are you referring to the back pillow cushions in orange or the accent pillows in solid orange?

The back pillows are part of the couch and I would only be able to add orange throw pillows. Definitely will be adding a brown rectangular coffee table with matching end tables
