Having troubles with facial angles in your drawing style?
Try a 3D sculpture of your art in your own style in a free program that is simple and very easy to use.
The program is called Sculptris and is a free off-shoot program from Zbrush, that program that you keep hearing about but either takes selling your kidneys or piracy to actually use.
If you download it and sculpt out a facial model, you can have references for your own work for all of time. No more endlessly searching Google for reference materials or twisting/rotating/flipping a drawing to see if there are flaws. And you can easily edit it to create more facial types. This way, you can make character references for any and every face and facial angle that you can think of.
The program offers mirroring right from the start, so your faces will be perfectly symmetrical. You can turn off the symmetry for things like scars or otherwise.
It takes a little time. For instance, I downloaded the program on Christmas and, in my spare time, this took a few days of getting familiar with the program (first day) and then sculpting for a few minutes each day, mostly due to my perfectionist nature. And this one isn’t even done. I still have to mold the mouth, ears, and other smaller aspects before I consider it done. However, I was so giddy over the possibilities that I wanted to share this with my fellow artists.
From now on, I have reference for a face in my own style and will be able to create things so much easier in the future.
I hope that this helps you guys and that you have fun with it.
