Dick Grayson
I started contemplating this custom years ago, but I ran into a brick wall.  The problem is, it is extremely difficult to remove the Robin figure's mask and make it look right.  I finally succeeded here I think.  The first step was to CAREFULLY remove the mask with a Dremel.  I then removed the bottom of his shirt and the buttons on his shirt.  Next, I sculpted on Grayson's sleeves and pants legs.  Finally, I primed and painted the figure.  I decided to go with the dorky sweater vest look.  When I think of young Dick Grayson back in the day, this is the way I envision him.  I guess it's the Burt Ward influence.
