Ottomans go in front of couches, not in front of accent chairs. So no ottoman(s) with these chairs. If you're going to put two chairs together, then pull them into the room (not against a wall) and onto the area rug, and put a small table in between them to make the seating area make sense. Remove the giant clock and hang art work. If the clock has to stay, then at least lower it, it's hung too high.

One large oval ottoman in fabric, not leather. A light stone or taupe woven fabric would work well. Good luck!

One larger one to share and please get some art hung lower and ditch that giant clock you also need a table between the chairs for drinks and probably a lamp.
