Glad I could help! I was also thinking, if you intend to make a full commercial game at the end, you will probably have redraw from scratch the assets based on Midjourney image generation just in case (I know it says you can pay a commercial license, but because it is trained on dataset without authorization, you never know when they get sued and the contract changes). You can of course reuse existing pictures as reference.
And for something less serious now: the male idol has a Japanese name, but the sprite was screaming “K-POP” to me!
