How increase the image generation textures?

Hello guys, how’s going up? I’m creating a ‘simple’ site thats do a photographic visualization from the users software print screen, I’m enjoing the result, but it’s looks like a bit polished, the chair fabric doesn’t has the linen textures, the brick wall, don’t have that realism… So I’m here to try any help that’s can improve this reliaf, this accurated textures. I’m using the nano banana pro API (from ai studio)
