EDM 4 - Draw Your Mug or Cup

At last!! I've finally done the next EDM challenge and I'm proud of myself for keeping at it.  I'm not completely happy with this cup because it's supposed to be white and I just couldn't do it properly because I kept finding shadows and reflections.  But then when I tried to represent the shadows and relfections it just looked messy and even less like a white cup (see stylized version).  Very frustrating. In the end I just put my own shading on it (final drawing). Here are some sketches, a stylized version and the final drawing.  I'm not sure which of the bottom two to post on flickr though.  Any suggestions please?
