Creating 3D models requires lots of work, experience, and training, especially if you're making something realistic. You need to know anatomy and how the human body works, you have to have a lot of knowledge on perspective, shadows, and many more things. Often, professional 3D modelers spend months creating a model. They not only have to create the sculptures, but also optimize them and get them ready for animation.

Hossein doesn't only create famous characters and personal projects. He has achieved great things during his career. Hossein worked with popular triple-A companies like CD Projekt on their most recent video game "Cyberpunk 2077." Hossein also contributed to video games like Royal Rumble 2016, Modern Life, Evolve, Atom Universe, Alan Wake remastered, Fallout New Vegas, and Batman Arkham Knight. He's currently the Lead Character Artist at WWE.

A website called Nuts wrote about Hossein and his work: "Born in Iran, Hossein Diba is a Digital Artist specialized in character realization for games, animation movies, and 3D prints. Since childhood, he has always loved painting and, as he watched the first movie of the Jurassic Park saga, he began imagining his future as a modeler. At the time, computer graphics were quickly evolving and Hossein especially focused on discovering 3D and its countless opportunities. His strong passion drove him to practice for years, becoming a specialist in modeling, sculpture, texturing, and shading of both characters and fantastic creatures. Alongside his passion for computer graphics and 3D, Hossein has also developed a deep knowledge of human and animal anatomy, which further contributes to the exceptional concepts and rendering he shows in his works. His artistic inspiration comes both from traditional artists, such as Rembrandt whom he admires for his portraits’ lighting technique, and from digital artists such as Rafael Grasseti, Luc Begin, and Michael Knowland. Hossein has both worked as a freelancer and as a team member on titles such as Royal Rumble 2016, Evolve, Atom Universe, and Fallout New Vegas."
