I took up a small job as a colorist for a webcomic. Here are two sample pages:
The first one is an example of what the comic will normally look like (drawn by Brandon Zuckerman), the second one is drawn by a different artist (Andrew Snook). The second one also had a considerably greater amount of effort put into it. I won't be putting that much work into the comic, because it takes too much time and I lost interest a few times.
