Blender High Poly Tutorials

Deqa

Anybody have any tutorials on how I can get started with high-poly 'image reference' modelling in Blender? I was wondering because I saw this video and I want to model a shoe for a game, based off an img ref & in Blender. I know there's a lot of resources for Max on here, but I was wondering about Blender in particular.

Thanks, any pointers would be appreciated!
