I decided to keep the color scheme for their clothing the same, but to give Jess and Lizzie slightly different hair colors and skin tones, just to differentiate them a bit more.
And here's a quick color study of Jess' room. Again, I decided to repeat the colors from the first comic.
And just a look at what Jess and Lizzie will look like in the room. I mainly did this to help me visualize the color scheme of the individual panels and decide where to place them for their discussion.
The new comic will be between 3 and 5 pages (I'm still working out the details) and will cover another sensitive issue in puberty: breast growth. After this one, I think I'll either move on to body hair or go more in-depth with the menstrual cycle. Eventually, I look forward to having a "your body and you" type of comic book put together. Anyway, that's all for now.
