Yes! that's exactly what I mean, great example.
If I can give you any advice: On the Tokyo Ghoul page pay attention to the line thickness on the outside of the characters, it's a lot thicker. That's what makes a character pop or stand out from the background.
You can use any style to draw but you have to be your own critic before anyone else is. If the hair on your character is in a sketch style and so is the shirt he is wearing then the reader cant tell the difference. I don't know if that's a dark background or his shirt, it looks the same as the hair.
Another thing that makes your characters stand out is using texture for the background. The backgrounds are a lot darker than the characters.
So in your case the Tokyo Ghoul page is a great resource for a quality check. That is all detail, line work and texture work that can be applied to any drawing. You still have to work on anatomy as well. This also depends on your style whether you want a cartoon or realistic look.
To sum it all up, my approach would be storyboard first, then focus on only clean line work anatomy. After that do all the detail work such as sketching , texture, screentone, and lastly word bubbles.
