This is a collection of the steps used to make my Model Base Two. I hadn't really been planning on making any new bases at this time, but I suddenly felt inspired to do one, and I decided to post the steps I used as I went along.
There would have been a flat, shading-less version, but I forgot to copy it into this file, and I'd already shaded the entire base by the time I realized.
THIS IS NOT A TUTORIAL, that's why it doesn't have instructions on it. The numbers correspond to the numbers in this comments section. You can use them to figure out what I did in each step.
1. This is the preliminary part of of the base. I do something like this for every drawing I do, except for my little (unposted) concept art sketches when I need to get an idea out and can't be bothered with proper proportions, etc.
2. I like to define where the breasts and the muscles near the shoulders are, before I start really sketching out the body parts. I never really make lines for the nose or mouth when I draw on paper, but I do when I draw digitally.
3. I started adding more volume and definition to the entire figure. As you can see, there are a lot of errors I corrected as I went, and I stretched out the entire torso, because it turned out to be too short this time. I also added little "sockets" for the eyes. Unless I'm just practicing eyes without drawing faces, I always draw those "sockets" so the eyes end up exactly where I want them.
4. I drew in the facial features somewhat in this step, but nothing else.
5. I didn't like how huge the base was (bigger than you can see it as, full view is not the original size), so I resized it to make it more workable.
6. Instead of using the tablet to continue making the base (which wouldn't make clean lines), I switched to the line tool, with the occasional pencil tool correction. I do this for all of my bases, so the lines are clean and easy to work with. I used the line tool to redefine the body in this step.
7. I cleaned up all but the colors I actually needed for the finished base. I work in bright, rainbow colors so that I can see what I'm doing, and the colors don't blend together and create problems later on. I do this for all digital art, though it's not always rainbow colors when I work in SAI (it's usually red and blue, maybe green and purple if I really need them).
8. I recolored the lineart to the colors I usually use for bases.
9. I shaded the base and changed the face and breasts so that I was happier with them, since I wasn't thrilled with them before.
Overall, I'm pretty pleased with the base, but I don't think it's the best thing I've ever made (probably since I haven't made one in a while). However, it's certainly good enough for the purposes of this example.
