Texture not loading on my model

So this is my first time creating custom item and even if I created a lot of things with datapacks I never touched items. For some reason after checking tutorials I setup resourcepack and everything works until I added a texture. I dont know why, but custom model data dont want to take textures from texture folder and my coding in json is correct. So I wonder if there is a problem with mc or is it just small change in json I didnt saw at first glance. MC Version 1.21.1
