Drawing Shiny Surfaces:
When you're drawing a shiny surface, like an apple or a teardrop, you want it to look shiny.  To look shiny, you need to add "glitter marks".  To do this you'll draw your "shiny" object.  I would suggest drawing a teardrop because they are easy to draw, but if you want to you can draw whatever you want.  So draw your teardrop or picture.  Once you've drawn that we'll add the "glimmer" marks.  To draw a "glimmer" mark, you'll draw a crescent shaped spot on a side of your picture(it dosen't matter which side).  The bottom of the crescent shaped "glimmer" mark should be flat.  Consult the photo below for an example.  PS, thanks for reading!
