You really did a great job picking out your first stuff...such versatile shadows and the best tools ever.. just in case you dont already have this-you might want to consider investing in a good primer too!
I remember the first things I bought from MAC were bright green shadows and yellow/green/pink paint tubes with no brushes. For a girl who had no idea what she was doing...let me just say it was a mess!! I was scarred for life.. (no wonder i'm more of a ruby woo girl!)
