Finally, the shading is done using a light-hardness brush on a multiply layer at 50% opaque, and light effects are the same but on an overlay layer.

Finishing touches are added, watermarks and/or signatures are added as needed, and it's posted. This one in total took me about 5 hours to do.

Now, the next step is to either scan the sketch, or take a picture of it with my phone and get it on my computer that way.

I physically can't use an art tablet because my hands shake too badly. To compensate, I use the paths tool with either default lines, or paths combined with ink for the lines that taper off at the end. This creates clean lines that cause an almost vectored look.

The major drawback is that this step can take hours, depending on complexity.

The image is ready for color.
