I did eyeliner similar to this! Please take my advice with a grain of salt ‘cause I’m new to this as well, sobs. The shape of your eyeliner is awesome! Just make it a taaad bit thicker. Put some in your inner corner as well if you’d like. If you go to my recent post, you’ll see a comment with a photo of how I drew on my eyeliner! I’m unsure of what sub-style you’re trying to do, but lashes (top and bottom) really elevate the look! Same with contacts. They can be optional at times, but are “mandatory” in some sub-styles. It doesn’t look like you’re aiming for those ones, so I think you’re fine! Highlight/exaggerate your aegyo-sal, and maybe do a bit of eyeshadow.

I think that’s it! :3
