I think what I'm about to say will more than likely go against what many people have to say, but it's worth saying for one very particular reason.
We are creators, and as such, we view and discuss our work as work. Our books aren't books to us; they are work. Our art isn't art to us; it's work. But to none creators, books are books, and art is art.
That being said, I believe people favor specific art styles over others, but I also think that sometimes we as artists confuse style for quality. Some people will even hide behind the wall of supposed quality they believe they're bringing, when in fact, they aren't bringing a lot of quality at all.
For example, in your gatchgirl drawing, your anatomy is fine, the pose is alright, and the color is fine as well. It's just okay. I'd even say that your sketch lines are alright too, though some people would argue that leaving sketch lines brings down the value of the art. In any case, it's not bad. But it could be better. You could have taken further liberties in the anatomy, the color, the posing, or the details of the costume. Or you could have tried better to realize the anatomy, shadows, and proportions.
You might say that you decided to be somewhere in the middle because that's your style. But you can't forget that you are in control over the style. If you choose to get more dynamic or more detailed, more realistic, it becomes a part of the style. So when you decide not to go that extra mile, is it really because of style, or is it because you want things to be easier? If it's because you want things to be easier, then you probably aren't putting in as much quality as you think you are. And when you don't put in more quality, more effort, people can pick up on that. They can sense it; they can literally see it.
Would it have broken your style to draw in the rest of her fingers on the hand that's resting on the ground? Would it have broken the style to choose a more dynamic pose rather than something where her body is scrunched up almost into a ball? Would it have broken the style to work with the colors more so they pop? Would it have broken the style to clean up the sketch lines further? These are things you could have done to make that one image stand out without so much as even having to redraw anatomy to make it more cartoonish or realistic.
No one style is better than another, but just because you use a different style doesn't mean you can get out of doing the same amount of detail. In some cases, you have to do more detail work if you want a specific style to have quality.
And I feel like I should say these things because you literally said your top priority has always been to do less effort and have more fun. If you want to be noticed, if you want to be seen, if you want to come out from under the shuffle, you have to put in more effort than the people you're competing against. You can't hide behind "style." It's up to you to make your art style strong enough to compete, and to do that, you have to give it more time and effort.
We as artists and creators may fawn over individual styles, but ordinary people who don't create content only see what's in front of them. They pick up on how much effort went into things faster than anything else. And effort isn't just anatomy or how realistic a drawing is. Effort is how well you thought out color choices, how characters are posed, shading, how many shortcuts you take, how well the different elements in your drawing work together. It's not always about rendering or being realistic. It's always a matter of effort.
(By the way, I'm writing all of this after just waking up, so I may not be explaining this particular concept to the best of my ability. Still, I hope not to offend anyone, but I do hope you get my general idea.)
