I have been learning and enjoying 3D modeling in my free time for the past 6 months or so, and I've been documenting most of my progress on Sketchfab.
My technique is pretty primitive as I have (yet) very little interest in some of the meatier aspects of 3D modeling (normals, diffuse- and specular maps, highly detailed models...). This is quickly apparent after a look on my profile.
I do however still have great interest in 3D creation, particularly humans and female portraits, so I decided to document my process for a portrait in the forums here. Hopefully it will be of help or of interest for someone.
My favorite aspect of low poly portraits (or characters in general) is that every vertex carry a lot more information than on a high poly model. For example, to create a more prominent chin on a character, you only have to move a handful of vertices. Making every vertex count on a model is something that appeals to me. Since I started out however I have increased the detail of my base mesh.
The process is almost always these three steps:
1st - Modifying an existing mesh
2nd - Drawing the texture
3rd - Posing.
