Yours is lovely.
I have done a number of Dresdens over the almost 11 years since I began learning to quilt. IMHO, they are much much easier if you precut your blades, then paper piece, a half plate at a time. In my second year as a quilter, I ramrodded a charity fund raiser quilt, for which I supplied all the more experienced quilters with PP patterns. They all commented that it was much faster, more accurate and easier that way.
