You're not supposed to look much different anyway. In my shitty pic I only have eyeliner on and I look almost the same without it. If you want to look slightly different, then you should try putting on a combination of mascara, eyeliner (and/or) eyepencil (the color depends on the effect you want to achieve) & eyeshadow.
Are you only using eyeliner? Make-up usually looks better when you use a couple of products together. Maybe try looking up some tutorials on YouTube to find out how to get the most out of your eyeliner, if that's what you want to stand out the most.
maybe the eyeliner is too close to your skin tone. Black usually is a good match for most girls and sometimes you have to put it on a tad bit thicker. Go over your eye lid a few times so it will show up on your skin.
Me too. The struggles of being a potato. I use liquid eyeliner but I love eyeliner pens they're so much easier to use. You should try mascara with it too, so it looks better. EVERY time I use eyeliner pencil it comes out too light, i'm sure it's because i don't press hard enough, i have black and blackest black.. so it's not the color. Eyeliner pencil isn't for me, i don't think it's right for beginners because it doesn't glide easily so it's harder to put on. I recommend trying something else.
