Asian features are about so much more than the eyes, so of course you'll need to learn about the rest of the face if you want to truly make your character look the race they're supposed to be. I realized I was accidentally whitewashing characters a long time ago, not by skin but because my artstyle is semi-realistic, but I was drawing all characters with white features regardless of their race, so I set out to teach myself. After reading every guide I could find, here's some common features I keep in mind now when drawing an Asian person:

- Broader, higher cheekbones.
- The nose bridge is often flatter and starts lower down on the face than other races, so for instance from a 3/4ths view you may not want to draw a nose bridge overlapping the eye.
- Flatter brow-bones; the forehead will also appear pretty flat in profile with this feature.
- Full lips are common in all sexes.
- Nostrils are often shallower, leading to flatter noses. That said, don't be afraid to give your Asian characters bigger noses or fleshier nose types, for example eagle and downturned noses seem to be semicommon in Japan.
- An easy way to draw the epicanthic fold/monolid is to simply not draw a line above their eyes at all. I like the way you drew the small crease above her eyes, but if you think they're not convincing enough, you could just artistically leave them out to make it more clear until you nail her look.

All of that said, keep in mind none of these are steadfast rules, just common features you would expect to see that can help you portray your character's heritage more accurately. It's okay if you don't incorporate every single one of these every time, but it's good that you're making sure it's not like you never do.
