This is "M-11, Rickshaw", an advanced-level paper-pieced block. It's not all that difficult, but you do have to take things slowly and watch all the angles. Be sure to cut your fabric pieces large enough for each section, and then be careful matching the seams when sewing the sections together. Mine isn't perfect, but it's better and took less time than one of the first blocks I made with diamonds.
