Is there a decent guide how to create line art or inking out of a drawing before coloring?

Photoshop's pen tool doesn't look very appealing/convincing. It appears that SAI's brushes and pen tool gives more smoother lines (and colors).

Here's one I drew a few years ago to use as a testbed. It is bad, but that's not the point.

Could somebody at least share some good Pixiv tutorials or tags that might be related?
