Here, have a Miss Victory. Having fun playing with the ink brush tool. Fatter ink outlines make for a more cartoonish feel. Got kind of a PowerPuff Girl feel going on here... It was kind of an accident, didn't realize the default setting for a new illustration was 72 dpi, but it's Fun Size (like those little Snickers bars).
Again, I hate doing backgrounds so I just phone it in with some black to transparent gradient fills...
I actually made tomorrow's Java Jaguar page using CSP instead of paint.net. I thought I would probably be playing with the new software for a couple weeks before trying to switch over, but it's so much fun to use I just jumped in. Still need to learn how to do frames and speech bubble tools.
Oh, here's a process gif for Miss Victory (who is a public domain character, so if you want to use her in your own comic strips, I can't stop you).
