>>8019368Sharpness isnt going to really affect how real your images look to begin with as it just affects the contrast between 2 adjacent pixels.
First thing I'd do get rid of the base, if you want presentation, the base gives it away as somewhat of a toy. Second is shoot over exposed so that the white background becomes pure white and loses the detail, can be easily done on iphone by holding focus and dragging upwards.
Last thing I'd recommend is trying to shoot with a longer focal length, you cant adjust that on phone cameras unless they have multiple lenses, so you're a bit stuck but something you can look into for next time.
Models got me into photography funnily enough
