Beautiful, challenging window. (Not strictly Palladian BTW - just a huge window with arched top.) I wish the builder had left you enough straight ceiling or ceiling height so you could do a single straight rod. But he (she?) was so busy creating a beautiful house that the window treatment needs were not considered. I have a feeling that to improve on what you have (which is well done even if it's not quite what you want/need), you will need an engineered solution costing $2,000+. What are your major current complaints about the curtains?

Thanks for responding. I might be able to do a straight rod all the way across the top. I don't care for the heavy drapes (they came with the house when we purchased 1 yr ago). They are a dk navy paisley Ralph Lauren that is much heavier than I want. Someone suggested running a rod across the top of the lower window just below the arch but another decorator said that would chop the window.

I think there are some good things about your window treatments now and some not so good things. Also the advice about running the rod across at the top of the first set of windows is probably your best bet. Yes it will cut up the window a little but in design you have to look at your options and pick the best one. Rarely is everything perfect. So yes it would have been fantastic to do that rod at the very top, but It isn't an option so you have to compromise. I personally don't think it will look bad in your particular case. Those are tall windows and by dropping down the rod you will cozy up the room a little, which is exactly what you want in a bedroom.
As for style, I am a big fan of just panels. You can change the style of the panel and add bells and whistles like trim if you want, but panels to me warm up a space, finish off a room and should never be too crazy that they draw your eye away from the rest of the room. I also like the romans on the other windows, and depending what fabric you use, you could also repeat those under the panels. There are many more questions to be answered and other details to be ironed out but I would stick with panels, drop the rod down to the bottom of the top window set, and pick a much simpler lighter feeling fabric.

I may be able to run a rod at the top b/c there are currently 2 rods on either side of the arch at the top of the molding. If I have enough space would you recommend 1 long rod at the top and just panels on either side and not in the middle? Would it then look too open? If I were to do that, how do I handle the privacy factor? I agree that I could use whatever fabric goes on the panels for the romans on the side wall. Would I need a heavier fabric or something rather light and open? Thx

Here are some ways others have handled similar windows...

Thx. I am also trying to figure out whether to keep it plainer and then add more accent colors in pillows since there is so much area to cover.

For a window this size, where the treatment will be $$$$$, I would recommend a solid color with beautiful texture that goes with a lot of other colors to permit later redecoration. No prints.

thx.
