Go to www.youtube.com and search buttercream roses. You will find several on there.

Sometimes it isn't your technique as much as it is your icing. I like to add some corn syrup to the buttercream, so that the edges of the petals don't look so torn. When you mix the buttercream, make sure that it's stiff enough to hold peaks, but not so stiff that you can't get it out of the bag without killing your hand.
