What were actually needing help with ?
Are you looking a completely changing everything ? Or are you wanting help with layout of existing furniture ?
Clarification may help :)

Change the window treatments. Shutters would look wonderful.

This dining set can add attraction to interiors, I guess.

I am looking for ideas on colours, paint, curtains, carpet, upholstery. We would keep dinning table and chairs as inherited.

We change furniture around depending if we need to use the fire which isn't very often. I must say the table does look better in front of the larger bay window and the lounge under the smaller window.
Thanks for your ideas so far, very inspiring.

You've got great chairs to have two different fabrics one on the back facing out and another on the seat and back facing in.
Something like these.

Ooh, there s an idea, thank you, Judy
