I did a lot of little girl groups here and there just to get more comfortable on stage. When you're in girl groups, it's a lot different because if you mess up, there's someone on stage to back you up, and finally I got to a point where I knew I could do it on my own.
When you're first learning how to do eyeliner, it's really hard to get both lids the same. A good tip for when you're putting it on, is to make sure your elbow is on a table. Make sure your arm's really stable. And make sure you have an eye makeup q-tip to get that really sharp line.
