Lava Lamp

This is a simple everyday lamp. I used a Lava Lamp I have on my desk as direct reference for the type of materials I should use and how the object should look.
I believe that the lamp looks very good and i think this is because of having a direct reference helps with understanding how the material behaves. It helped with how imperfections on the surface should appear, like fingerprints and scratches.
On the other hand, I am disappointed in the glass part of the lamp. I couldn’t figure out how to add the opacity from my texture mapping into the model correctly. so i lost the dirt effects i had on the glass and was left with a perfect glass appearance which conflicts with the imperfections across the metal.
