While the "fail" here is still pretty close to "fab," there are a few things to keep in mind when working on a smokey eye. The black and gray version is easier to turn into a total fail (especially for beginners), thanks to black shadow and liner's ability to make the eyes appear smaller. The bronze and gold version reflects more light, doesn't close off the eyes, and is a lot more daytime friendly (while still remaining glam enough for a night out). For day, try using a dark shadow instead of liner near the lash line for a softer smokey look. Touch it up with a smudgy kohl liner if you're wearing it out at night and want more drama. Be sure to set the kohl liner with dark brown shadow to keep it in place.
With makeup, attention to detail is what takes a look from fail to fab or "hot mess" to hot. Clean your brushes between colors or use several different ones at a time. Pay attention to finishes, putting shimmery shadows where light should be reflected and matte ones where you want shadows, and balance these out for a light-reflecting look. Always even out your skin tone before applying extreme color to any part of your face, and be sure to find products with the correct undertones for your skin.
