The round ottoman will be good as for the cabinet IMO a bit dark right next to that very light DR I think I would hang the art in the DR as it will be too high in the sitting room, just add a beautiful tall vase filled with fresh flowers in the sitting room. I would look into white washing the cabinet, it might be a bit of work but could look very nice

Does your foyer have dark hardwood floors?

@Lala Yes, I have added a picture of the larger view including my flooring.

I am also thinking of switching out that art work for this one: https://www.ballarddesigns.com/bd/412936?SourceCode=BDG006&intlShippingCtx=US%7CUSD&CAWELAID=120245430000510750&CAGPSPN=pla&CAAGID=68602813413&CATCI=pla-296303633664&kclid=8028ba57-eea8-41a1-86c0-2192d0e287b9&gclid=EAIaIQobChMInrim7NKa6AIVysDACh3ftAAQEAQYBCABEgKBmPD_BwE

I also plan to find a round ottoman that is smaller to fit the space better.

I don't see any reason to change the finish on the wine buffet. The vertical art would be a better choice and a neutral round or oval ottoman will not take up so much visual space.

@BeverlyFLADeziner Thank you so much! This is the vision I had originally! You don't think my Dining Room table will be an issue?

A mirror, bar tray and lamps would look beautiful :)

Here is the final product! I went for a different canvas and also added a circular ottoman that works well with my chairs. I may add a fiddle leaf fig tree to one corner but other than that I think it came together nicely!

Looks so much better. You have lovely taste. I would move the buffet to the right a little as all the "weight" is on the left. Then perhaps add a lamp. The table between the 2 chairs could be a little bigger. Do you have another table around the house you could swap.
