After the last picture, I relized I really needed to sit down and figure out how my characters compared to each other. So, I started trying to draw all 6 of my characters standing in a row. After about 4 failed attempts, due to the fact that I couldn't get proportions to work out correctly at all, I went super precise and busted out the ruler and calculator, figuring out exactly where on the page all of the tops of their heads should be, and then drew from there. After screwing up Darlos and Ricka the first time, I erased them and decided to start with Ricka instead, since I seem to have more a "feel" for what she should look like. And, it came out rather well from there on:
And there you have it. All six of those characters in perfect proportion to one another. Now with this as a reference, I think I can comfortably continue my comic.
But first! College finals. Sigh...
