Sorry, but I don't get how you can sell this as hight quality high res pixel art. Even on the low res imagines you can see lots of: orphan pixels, washed out/ unclean texture parts and uneven pixel sizes. This is clearly AI generated and should be tagged like that. Everyone working with pixel art or even doing themselves can see that. And then you wanna charge 10€ for that. I doubt you will be successful with that. And at that quality you don't need any watermarks, noone will copy. It's annoying that itch is flooded with that stuff.

are they not usable in any game? to me i do not agree to your comment but i appreciate , i clearly put a good effort in fixing the design in 100% fit pixel the file looks amazing if you don't see the benefit i recommend you can check my other ones they are not generated they are hand crafted go for it thanks for your concern .:)
