I want to draw my own pictures on the bedroom wall. I don't know what to draw, and I don't want to invite the decorator. Please attach some pictures to follow!

I'm going to draw a picture on the wall, too. I'm going to draw a 3D effect, and I'm still designing it. I have some artistic skills, so it should be no problem. If you want a black-and-white painting, you should first choose a good picture (landscape, plants, etc.) and use the ink painting method (acrylic pigment), which will be more natural, but you still need some other colors, so that it will not be monotonous and more lively. This is my personal suggestion for your reference only.
