I couldnt export the texture for this

So this is kinda my comeback to Blender, just been fooling around without any guidance so this was probably 100 times harder than it should've been and I know it have a lot of mistakes but it was a very good practice and I learned a lot of things during the process. I have no idea why the textures just didnt want to load I made some simbolic colors in here but it looks completely different with the right colors and I painted it in the sculpt tab but anyways... gotta keep on practising...
