Sometimes you just have to work with what you have. IMO, seeing "high water" curtains would be more of an issue than which pocket you used on top. So, I would arrange the curtains so they all skim the floor.

I would consider some brown, cream and grey pillows for your sofa. They will help tie the colors of the two rooms together and lighten up your sofa.

It would also be nice to save up for a long console table to put behind the sofa. You can add a lamp that will give you some extra light and an interesting height change. And it will break up the bulk of the sectional as you look into the room from the kitchen.

I'm not loving the brown curtains with your sofa and I'm not loving the white curtains with the brown curtains. I would try to find something that will look good in both areas to unify the space. Maybe a pattern, to add some interest, as you seem to have enough solid surfaces and upholstery.

Nice windows but you have devalued the room with what's been done. A better result would be high and wide voile on front of double track with a black out/ lining on the back track. Dressing voile to enhance the window and use the black out or lining for privacy .

Both the high water look and the too low rods do nothing for your room. Get longer drapes and raise the rods. A more cream color would work better.
