You have nothing to loose but time and a small amount of money (relatively speaking) in material. I suggest two things:

First, stick with laytex based paints. This will ensure you don’t have adhesion issues with whatever’s already on your wall. Ditto for whatever might wind up going on top of what you paint.

Second, try to avoid adding too much texture. When it eventually becomes time to repaint it will be easy to change color, but prior texture will come through. This is true regardless of whether you change up murals or go back to a solid color.

Or, you do you and to nuts! It is your house after all.

Hi, fellow home artist! I have a music room, the ceiling of which I painted as the winter night sky in glow-in-the dark paint for the stars. So, the ceiling is really imitating the winter night sky.

I think you have to be the one that originates the mural fully. What feeling do you want your rooms to have? For me, I’d go with a relaxing bedroom, a strong office, and a lively kitchen.

Depict a painter painting a mural on the wall of whatever room it is

Maybe paint things that reflect your interests? Be careful to pick long-lasting ones, though. Otherwise future you might think present you was a goofy idiot… Which could be endearing, really depends.

Generally, I suggest you consider painting things you cherish. You’re putting in effort, and you’ll be seeing the result often, so it might help to pick something you care about.

Less is more, consider the flow of the room and what furniture and people tend to do in the room. Use a simple background and/or muted/lowkey details for most of it.

Highlight a few cool interesting things up front, using otherwise empty spaces that need it. Think more like wallpaper that coordinates with the whole room, and less like a wall of comics that just uses up the entire wall space.

I hope that makes sense. I watch a lot of dumb home renovation type shows with my spouse, and this mural thing comes up on occasion. That’s my only qualification.

Horrifying scenes from world mythology

I had dreams of painting places in my room using an etch a sketch style string and stepper motor setup but never got around to it. Plus that is way past my coding skills level if I’m being honest. Right now, if I could do anything, I would go with an O’Neill cylinder with the full 3d perspective view from within a 9.1 km diameter space habitat. I have different ideas for technology and what it would look like, but this covers the basic concept in 3min: https://www.youtube.com/watch?v=Z2d_0l5ycRM

Your favourite childhood videogame characters. Seems to be a popular theme.

You say bedroom, home office and dining room. I say:

1. Play on a basic dreamcatcher theme, big long straight lines like a spiderweb crossing walls following the edges of your furniture or breaking them, and where lines connect into a junstion, paint a frame from them, like in a center of the web, and there put a drawing of thing you dream about, may it be from your past pr in your plans. Lines may be just a bit different from your wallpaper’s color so they aren’t too intimidating. Luminiscent paint works kinda great in the bedroom context, so you can paint some outlines with it.

2. Office space shouldn’t be too distracting, so maybe evenly spaced thin vertical panels may work. I don’t know what you are working on, but I suggest simple illustrations of this process, one picture at one panel, with a diagonal cut-offs on the top and on the bottom with them repeating on each side, like you are looking at a film.

3. Organic vegetational shapes, green-yellow-red color palette. I don’t know your tastes, but a powerful Broccoli Boi drawn like a Kool-Aid Man can be a center piece of such composition and a fun conversation piece when you’d invite someone to eat there.

I’m so down to paint a bunch of little psychedelic pieces in a house of my own one day. Might be something you like.
