Here is a behind-the-scenes look at the making of the Overpopulation comic. The initial word doc:
Some early sketches. A few of these were drawn "actual size" in order to trace them later.
Once I had all the images pretty close, I traced or re-drew them on the comic board.
Then I began inking the image itself with pens.
With most of the fine linework done, I used a brush for the large black areas.
On the computer, I clean up some mistakes and redo the lettering (for easier reading).
I realized later that the final tier of panels had images that were fairly similar (head and torso shots), so it might have been better to mix those up a bit.
You can see the final image here.
