Hello!
I am an artist and I have expereince in pixel art and game sprites and backgrounds. I have posted my own game demo here on itch too, I created all the sprites and backgrounds myself: https://saliham.itch.io/the-cloud-weaver
Other than that, I also created a pixel art game just to practice game design and pixel art.
You can check it out in my portfolio: https://drive.google.com/drive/folders/1oYCWhRVveLvq9g7cztS7GH7JfCKJC_Zh?dmr=1&e...
As for using AI elements as placeholders I am completely fine with that
