Honestly, I don’t see a problem. It’s just when authors portray their characters very stereotypically, that’s when people get offended.
I’m Asian and there are a lot of stereotypes, like “Oh, they’re really good at math” or stuff like that because although I can get a passing grade in math, I’m not the greatest at it. The one big thing that bothers me is the eyes.
More specifically, these eyes. 
Yes, it’s okay for Asian characters to have them, but that doesn’t mean every single person has these eyes. Nobody in my family (my mom is Chinese and my dad is Japanese) has these eyes or anything like that. Personally, I have wide eyes. So does my dad. Yes, I do know some people with eyes like that, and yeah people do have them, but not everyone does.
Second thing. Not every person, especially East Asian, wears clothes that cover up every piece of skin. Some people do, that’s their preference. But I’m okay with not wearing long sleeves in the summer.
Third thing: I know nearly every single Asian episode character (I see at least) is either really innocent and angelic or very tough and aggressive. Personally, I’m definitely not innocent, but in all honesty, I get freaked out from murder novels, so that’s a hard no on the toughness.
As long as you do a bit of research and may sure nothing is offensive (I’d suggest a beta reader for double-checking) then I think you’d do fine!
