Oh some excellent mini's shown here and some excellent advice! The one thing I would add is watch the "l-r swing". This is caused at the beginning and end of the seam. Make sure you are starting your seam exactly on the 1/4" mark and keep that short seam straight. We tend to curve in and out on the beginning and ending of our seams. Not noticeable on pieces larger than 2', but like previously mentioned, every mistake is magnified.
