While briefing you description that you need a Promotional video 3D modeling.
I am a skilled 3D designer and animator that have 10 years of experience. Below you will find specific jobs and examples of relevant work.
I used Blender, and Maya 2020, to create these animations. Also, I can use Zbrush as well. Textures, and compositing, were all created within the Adobe Suite with programs such as Photoshop, and After Effects.
