My royal icing flowers turned out better than I've ever made them. In the past 3 weeks,I've only made them with buttercream.

My royal icing was perfectly creamy, no grittiness just very well done,and they look really good. Is there a way of getting buttercream to look as good as the royal icing looks?

What type of flowers?

Ribbon roses, swirl drop flowers and star flowers. I'll have my class number 4, level 1 Wilton Decorating basics on Tuesday. So I made my flowers ahead of time to go n my final cake.
