There's really not much you can do in terms of those three things, outside of varying how you do your eyeliner ..

Grab some brown eyeliner, which is a nice, neutral colour. Outline your eyes with a tiny line all around, and use sufficient mascara more towards the outer corner of your eye. Find your face shape, and look up the best way to apply blush that will accentuate your face. Throw on some light pink lip gloss and you're good to go! xoxo

1: Blush: You can try and pinch your cheeks to find the right color for you first, u pinch them, and your cheeks will go a color, that is your right blush color. Then try to find a blush thats right for you. Cream or powder.
Cream blush: you can your ring finger and pat it on.
Powder blush: you should use a blush brush.
-remember not to put too much on, or it will not look natural
-if you have a wider face: apply blush on apple of cheeks, but then go up towards the temple, this will help to make your face to appear longer, and less wide. If you have a long face, just apply on apple of cheeks.
-too find apple of cheeks, smile, and the round part that sticks out on your cheek is where you apply the brush.

- Pencil eyeliner: this can go your waterline, and your tiline (tiline is the inner rim of the upper lashes, like the water line, you have to lift up eyelid to get it).

there are many ways to do eyeliner, i reccomend looking up videos on youtube, and pictures.

3: Mascara: You can use water proof, or non-waterproof. Waterproof will last longer, and hol a curl longer. But is hard to get off, and can get more clumpy. non waterproof, is easier to take off, but comes off during the day. And does not hold a curl well.
-i reccomed using an eyelash curler before applying mascara.
- you can get any color of mascar you want, pink, brown, black etc.
-You can also look up videos on youtube for howing to use the mascara brush while applying it.

2:Eyeliner:
-liquid eyeliner: this goes on the top of the eye, do not apply in waterline. I personlly don't like liquid liner. But it gives more of an intense color.
- Gel eyeliner: I like this cause it lasts awhile, easy to apply, and its not too dramtic. This also goes on the top, but you can apply just below the lash line (very thin).
- Pencil eyeliner: this can go your waterline, and your tiline (tiline is the inner rim of the upper lashes, like the water line, you have to lift up eyelid to get it).
- can also get any color you want. Bright colors=fun and unique, brown=natural, and soft. Black= defined, and intense (not overly intense though lol)
-you can make the eyeliner on the top at thin, or thick as you want.

hope this helped
