The metal isn't very shiny. The skin is most likely made of black lines and black dots. Those dots and those lines must be avoided at all cost, seriously, they look horrible, they just dont fit in a skin. The metal is very very blank, its only a boring grey, without not really any shades, for darker shading i recommand a blueish tint, and you must also brighten up the metal. the sword's handle is horrible: its a grey rectangle with few blurry red dots on it. Oh and you used filters on the flag holder.
Bad color choice, grey and red, only two colors, that's already not enough.
