Bike

Very cool! I like how you added textures and you how you tried to make the different colors of metal on the motorcycle stand out. If I could suggest something, though, I would suggest you study shines more closely, as shines can take many different shapes and forms when reflected onto metal. The shape of the metal determines where the light will hit, along with where the metal is in the first place.

For example, take a look at this picture of a motorcycle: [link] You will see that the shines are all different. For instance, the shine on the glass is like a sharply rendered rectangle curved onto glass. The sides of the bike have more subtle shine, so that there are soft edges. The shine on the wheels is more soft as well, since the material is rubber. Rubber is not a very lustrous material, as you know.

This should all be easily seen through pictures, but it's still good to keep in mind which materials will be more shiny and which will be more dull.
