Hello!
I am currently interested in this position. Through the times I have received commissions which required difference in culture in character design, so I think this job might fit me well. I'm also used to doing character concept and developing different types of expressions for it.
Here are some examples. Not all are character design since I also had to make illustrations AND character designing at the same time from scratch;
character design and illustration

clothing design + Sprite artwork

chibis with clothes differences + Character Design

character turnaround + Character Design

Here you can check my demo reel video for character design I had to make last year with my creative process:
