I like second plan! That space will fit the wardrobe perfectly. Take all colors from the art. The colors can be lighter or darker than the colors you see in art. Take "Venice" with you to paint store and they might be able to help you choose good colors. Idea: paint four walls the same and see if you like that. If you feel the room lacks interest, then paint the accent wall. Choose a pale green that harmonizes with "Venice" and a darker green accent. Yellow + red accent White + blue accent

I agree whole heartedly. I also agree on starting with the bed. The bed should be the "hero" of the room. Night stands are always needed, but even they do not need to match. Then figure out exactly what you NEED for storage in the bedroom. There is no rule that you have to own a dresser if you store all of your clothes in the closet. Will you have a TV in the room? How do you plan to view it? From a sitting area, in bed? A sideboard with storage or a media center may be a better choice for you. Do you have a seating area, or at least a chair you can sit on and tie youe shoes or put on socks. Buy furniture for your specific needs, buy the best quality for the work horse pieces you can afford. Don't forget lighting, and a mirror of some sort. Look at the photos of Master Bedrooms here on Houzz, you'll get an inspiration for mixing and maybe land on a style that appeals to you. Fall in love with a piece, the green tags show you where they came from, or ask the question. Have Fun!!

Start with super straight and flat wall studs and the $$ premium that that will require. Then the $$$ premium for the plasterer and the double layer of upgraded stock.

Unfortunately, I do not have a photo for you and have been unsuccessful in downloading my sketch. I think I can explain better what I meant. Your window behind the bed cannot be centered behind the bed and presently looks a little awkward. To remedy this, I suggested framing it with wood trim and creating another "fake" window alongside of it also using wood trim to frame it. Both the fake and the real window would get two rows of louvered shutters, a top row and a bottom row. Obviously, the lovers on the fake window would remain permanently closed. They are there only to give the illusion of another window. The shutters on the bottom half of the real window would remain closed, but the louvers would open to allow light and air. The top shutter could open to access opening and closing the window but most of the time, just have the louvers open for light and air. You will have created a bank of window that your bed could be centered under and I think it would look nice. I would use a headboard with wood or metal spindles that allow the light and air from the real window to pass through, yet give you something to prop pillows against. I must say though, if you did not want to do this, I love the recently added photo by Anne dee with white drapes, gray walls and some framed pictures that really help balance the awkward window. That was a beautiful room and looks a lot easier to accomplish than my idea. From your photos, I am not quite sure you have enough wall space to do it exactly like that, but I am sure you could experiment with the concept and come up with something lovely based on that idea.
