I rolled a few simple prompts (sometimes they are all you need) in different versions and styles and got one that was really close, and the Van Gogh brush strokes were really cool. I then upscaled the image in Visions Of Chaos, then used layers and generative fill in Adobe Photoshop to make it look more like her, with a little goofy eye and black stripe down her snout. I sent it off to print as a stretched canvas, and we are both (well, all three of us) incredibly happy with the new decor!
