Hard question to answer, because Doom used a wide mix of styles to make its graphics:
>graphics painted by hand on a computer
>graphics drawn with pencil and scanned in then processed
>graphics digitized from photos, clay sculpts, latex models, toys, random stuff they had just lying around, Kevin Cloud scraping his knee on his way to work in the morning, etc
>graphics from resource libraries (textures)

Pre-rendered 3D was about the one thing they weren't doing to make sprites.
Just make sure the shading and lighting is consistent and good.
