I think it looks cute now.

Yes I’m planning on painting all of the red. Anything g and everything that needs paint. Replace lighting fixtures.

I would make it all white ..the decking I would paint Grey . Metal paint doesn't really last at least not in harsh climates ..it peels , leave the Windows alone ! Beautiful house ...put flowerpots when it's all white and some grey touches ...pretty ! Good luck !

I've read that painting a porch ceiling a light sky blue makes it less likely bugs will build on it because they think it's sky. (Not an expert; sister says it works.)

Why are you doing a whitewash on the bricks?....will that really look fresh and new?....what is the finish now?...To get the most for your money and efforts I would do a full cover paint on bricks in even a satin finish...in a color...as is ....the red part is the most striking and unique,feature of the house.......what is your climate...are you coastal ?....what does the neighbor hood look like ?....will the paint color be the only thing to distinguish your home from the others?...from the proximity of the home next to you I would say you do want your home to blend in somewhat... not stick out like a sore thumb... but have some individual personality...

Don’t know what your budget is but I think the place to distinguish your home is the railings....replacing them with something more interesting to add detail or at least using a color there....the ceilings above the decks look odd in the pic ?....they may need to have ceilings installed that can be painted to follow the theme of increasing the visual with the railings and the porches....contrast is needed here especially if you plan to keep the brick flat white ...

It looks like the front faces the view. If budget allows, you could do something like this with glass to open your view and open the front of the house. You can either frame in the glass or not. Lots of deck photos on houzz using glass.
