Following the advice to look for "fakeness" markers I would mention a few recurring ones: 1) unreal background (like monsters or distorted images) 2) strange-looking moles or birthmarks (white, very round or else) 3) distorted texts and logos on clothing 4) fabrics of the garments don't look real too 5) jewelry gets distorted or multiplied 6) glasses often look fake on the edges

Nevertheless this looks impressive.
