Here's a quick walk through of the process I usually go through:
First step is obviously a sketch. This is usually where I'd stop in my white sketch book.

Then I'll add ink and whatever other finishing touches it needs. On this one I added a white halo to help the drawing pop a little more.
Here are a few other drawings I've done in the past little bit:
