>>3942662That's why I called it mechanical-looking generic cg. I personally prefer thick black outlines, but anime style is more and more about thin and colored lines, soft round features, and making the lineart as subtle and delicate as possible.
You'll notice that there's a lot of weight to the lines in the sketch, and they could have easily cleaned that up and used that as the lineart. But they opted for the thinnest lineart imaginable because it's difficult to see the lines after the image is colored. It's really about making a guide for color fills.
This one is a little better, but still follows roughly the same principles I mentioned. If you want to get really bold and dynamic, then build up your lines like you would in any other style.
