I'm drew this for my new friend, byun-baek. She's a new deviant here just like me (joined just this week!), so please welcome her warmly and give her lots of encouragement and support! Byun-baek, I hope you like it! I don't know if it turned out good enough, so please tell me what you think! It's a little harder to draw someone I'm not very familiar with, as I don't have a good sense of "how they look," so critiquing would be nice, if you see any mistakes, because I do want to learn from my own mistakes. Thank you so much!
