Made myself a new iPhone background. Enjoy.
For the background pattern I used this pattern from Wikimedia commons: Japanese_Wave_Pattern.svg. [wikimedia.org] It’s available under a Creative Commons Attribution-Share Alike 4.0 International [creativecommons.org] license. That means this image is also available under the same license so go ahead and do what you want with it.
The daruma was traced from this image also on Wikimedia, under this same license: Daruma_doll,_cut_out_03.jpg [wikimedia.org].
Dimensions are based on my iPhone 11 Pro Max. With parallax turned off the daruma’s sit just above the dock. Your mileage may vary.
