Going to make custom models, need help

[Sir Teatei Moonlight]

You'll have to start smaller than "remake a game's models in the style of another game" if you are legit starting from "do not know in the slightest". There's many steps you have to get down first.

• Learn the basics of the program.
  
• Learn how to make simple objects like chairs and donuts.
  
• Learn how to make more complex surfaces with good geometry.
  
• Learn how to unwrap models and texture them.
  
• Learn how to make bones/armatures and rig models for animation.
  

That's probably the main stuff you need to know for making a tMR submission.
