I designed him that way for realism, he's a royalty from an influential kingdom who loves fashion and there's no way I would give him plain clothes.
But I do agree this design is very suck for comic and animation, and many others of my design too have same problem. I don't make comic, but I weigh in because I frequently make art featuring same characters and clothes.
You're good, don't worry!
the simplest practice is just sketch them continuously from different angle with different expression, you will attain consistency after sketching 10+ drawing. Just keep drawing and making craft!
Good luck in your craft!
