Hi,
For the longest time, I would keep drawing things in Photoshop, and then turn to see all these gloriously smooth lines that other people drew on their pictures here and other art gallery sites. I asked myself, "How in the world did they make such beautiful lines when mine always are a little jagged?"
I finally discovered the answer to this question. Enter: the Pen Tool.
I am NOT an expert in this thing, and I doubt I will ever be, but I'm practicing this by redrawing old pictures.
Some of these drawings I'm practicing cel shading on. Others, I'm just running a large soft brush for shading.
Here we go...
