although its actually a mac 10, not an uzi,
the models themselves are good quality, but you really shouldent paste images of the real gun on the side, it just doesnt look quite as nice, asif you were to texture it from scrath, (providing you are good enough at 2d art), the spas12 is nice, and good attention to detail, i doubt it says spas12 on the actuall gun, but you should make the text a slightley lighter colour than the gun frame so you can easily read the text from other angles.
