Yes yes think your white shelf would look nice at the bottom of the stairs. As suggested by carolins Not sure about your dancing butler moved to above your sofa other side Think it's a nice picture but maybe to small for that wall And wrong shape better with a group of pictures Coffee table maybe you don't miss what you never had We always had one But on moving to a small cottage Thought one would take up to much space So tried without Hated it oh dear Where to put drinks Ended up with a small ottoman with top that when Turned over are also trays And the ottoman can be used as extra seating So now I don't bash my legs on a hard coffee table

Where can I find these wall art?

Etsy really is a good source for art; you may be able to buy originals as well. Just search "Iris watercolor" and browse - many good choices there. Good luck!
