Please tell me about the two pictures below. Come on, photography experts

First, the lens quality is not high enough, or the camera quality lacks transparency. second. The aperture is too small. The aperture of an APS-C camera should not be less than 8, especially the D3200 camera with high pixel density. If you use an aperture of 8 or 6, it will be much better. There is no problem with the exposure, but the bottom plate is very reflective, so I shot at a slight angle, and then when the film was released, the saturation and sharpness were slightly increased. The picture is reddish, adjust the color balance, or change the color temperature. I don’t know if the sensitivity is too little, not too much. The picture is just rough. PS, this skirt is so ugly haha.
