You might want to check out this Course: BASEMESH: Create Stylized Characters Quickly with Blender
or maybe this playlist. NOTE: This includes the above-mentioned course: TRACK: Character Creation with Blender
The playlist starts with CORE: 3D Modeling and CORE: Sculpting. If you have already done those you can skip them. I personally would put short film character production and introduction to character modeling before pothead, but knowing Kent there is a reason he has it in this order.
