Drawing Butterflies

Miss Moana asks me to draw butterflies for her a lot, and I'm tired of doing pitiful round-wing things. So I've decided to learn how to draw a butterfly. I traced one from our field guide to get the shape and I've been trying to practice. It's not easy, I can't get it right, but this is only the first day. These were done on Paint where I could flip and superimpose the left side to the right to get them exactly symetrical. These are even on both sides, but still not right. Drawing it in pencil is a lot harder, and it's been a source of frustration to me today.
