Concept Product 3d modeling and rendering

Hi!
This is a 3D model I did for a client who came up with a hand sketch. He wanted to see it in 3D and also wanted to see a 3D render as well with the material he desired. He was so happy about the final image and loved the way I emphasized the details of the concept.

I used 3Ds max 2021 for modeling and Corona Renderer 5 to render out the image. Feel free to leave your ideas.

Thank you!
