Not a bad start at all. Of course, that's all about modifying shaders and implementing new textures to a model. The same sort of "chroming" can be applied to almost anything in the game that has a texture and model, such as weapons, map objects, vehicles etc to make them look better/cooler. However, sometimes the "chrome" can look too shiny, and can detract from the detailed textures underneath. So experiment with image editing as well, in this case, adjust the transparency level of the chrome texture to increase/decrease its intensity in game, and also alter the actual textures of the model as well, increase the details however you want until it looks good in game and you find a good balance of chrome intensity and texture detail.
