@CelestialNavigator Fun fact, actually, in regards to your number two. The reason why superheros are traditionally drawn with underwear on the outside of their pants is because of the limited capabilities of color printing back in the day. They couldn't print in a great amount of detail, as printers there put down one layer at a time (black, yellow, red, blue, not necessarily in that order) and so the edges didn't always line up, which meant that if a character had a lot of detail on them, it would get blurred in a good number of issues. However, they still needed to have some color and lines to break up the overall jumpsuit design, so they popped a pair of panties over everybody's pants and boom, you've got a bit of design interest and color and line work all in a neat little package.
Now my main character design pet peeve is seeing sci-fi designs that don't have any explanation or visual cues as to how they work. To me, Sci-fi is meant to show a reality in which a theoretical/probable part of science (like wormholes in interstellar) is available to people and what this might mean to the fictional society, or how it might affect how society evolves and how the characters deal. So if, say, you've got a character that can summon up fire in their hands, I want to know HOW. I don't want handwavium, I want to either see tubes and a fuel tank, or some explaination as to how and why they can do what they can do.
I also really dislike it when all the characters in a series conform to a single standard of beauty. Big boobs and trim eyebrows for ladies, tall, buff, and not partiuclarly emotional for men, that sort of thing. It's boring to me.
Lastly, I really, really hate it when no thought is put into the colors and values used, especially when those things are super saturated. I want things to be separated according to some manner of design, be it shadows or the opposite hue, because otherwise I get lost in the design. Either that, or my eyes get burnt out via too many saturated colors.
