Every week we'll have a new prompt. All visual artistic mediums are welcome whether it's pencil, paint, digital, sculpture, embroidery, or whatever medium you prefer or want to try. Prompts might include a technique, style, subject, color, or other inspiration. Creativity is the point so feel free to stretch the prompt as far as you want.
If you missed a prompt, you are still welcome to post your project later. Please include the prompt in your post title.

You've already covered many aspects in your list.
I would have suggested 'Smile' but I think your '25 joy' could very well cover that already.
Regarding the prompts:
Regarding the medium used, maybe put an occasional challenge? Anything one can think of in order to challenge ourself out of our comfort zone and our (beloved and so comfy) personal preferences ;)
Things like 'use a medium you would normally not' (ie, I would use my iPad instead of paper and pen), or 'use a limited selection of colours' (or colours you would not use, or just B&W),...
How about "fediverve" or more specifically Lemmy to get some more art out there related to the place
