Not bad. Just a little recommendation...maybe more than one. I would stay away from white until you have more practice. It shows too much. Get an Add a quarter inch ruler and the back will be straighter. If you don't have one, you can cut the excess fabric on the back with a regular ruler, making sure that you make your seams 1/4 inch. When you are done adding all your parts add a quarter inch all around as your seam allowance.
