Got a few requests to upload this over here. I'll need to update it later, since at this point it's a little bit dated.
A digital painting tutorial briefly explaining how I paint in general. This is a tutorial on technique only, and is done under the assumption that there is a prior understanding of light logic, anatomy, composition, and personal stylistic choices.
This is text heavy, but the text is helpful, I promise. If you don't like to read, the drawings of the spheres (which I'm aware are defying the laws of light logic) are placed so you can have an easier understanding of what's happening in each step visually.
Keep note that I'm not very qualified to teach anyone anything, and this obviously isn't the only way to paint digitally. It's simply my thought process when painting as I have learned it. So just take it as a guide, and use what is helpful to you, combine with other techniques that you like, etc.
Hopefully those of you that requested this enjoy it!
Correction in Step 2B: My neglecting to proofread allowed a mistake to slip by stating that cast and form shadows are basically the same. Let it be known here, that form shadows are softer blends, cast shadows are harder, or not blended at all.
A Note on Blending: I forgot to mention how I blend and soften edges in this- and I do so with other color and the eyedropper tool (which you can quickly access with the option key on most computers, or set up as convenient to you). Because pen pressure is on, just place a midtone stroke on your dark, eyedrop it, blend it according to pressure. It's the same concept as how you would blend paints or colored pencils.
