I am a newbie in Blender. My target is to become a Blender’s trainer or animator.
Currently I am still in training via tutorials downloaded through the links given by Hirsig, Neal. Based on the current tutorial, I found some issue on the KnifeCut which the video activity result is not same as what I have tried.
Technically your result is better, keeping is all as quads where in the video there are lots of triangles (bad).
The difference is probably due to differing blender versions, where yours is the newer and hence the improvement
