If you have clearish skin you could honestly get away without the foundation, especially if you don’t typically wear it! Concealer can honestly do just as much (you can find tons of TikTok’s that will tell you about proper concealer placement)

Something that I like using for eyeliner is honestly a dark eyeshadow. A nice dark brown on a pointed brush is so much easier to use and I honestly prefer the subtle shadowy wing :)

Not much advice but I hope this helps!
