While working on this model in a ZBrush program I decided to try a render of a transparent glass. In addition, I continued to experiment with the usage of noise, like I did on my past works.
This time I used the noise tool to create the texture of a rusty metal. In addition, on this same work, in combination with noise, I tried different ways of masking the model to highlight only certain areas of the surface to paint them in a more detailed way using polypaint.
Also, when rendering the model, I first tried working with light in ZBrush for a better design of the final render.
The final picture was rendered in ZBrush and composed in Photoshop.
