I recently acquired the Iron Studios Superman vs Doomsday diorama and love everything on it except the supes portrait. I checked it was removable before I purchased it as I was planning to do a new head.
Anyway here it is as a work in progress (original head is the coloured one of course).
It's actually moved on a bit from these pics as I thinned out the jaw and cheeks. Still plenty to do though: eyes need refining (maybe moving away from the nose a bit), hair smoothing out and detailing, mouth shape / teeth etc and so on.
Any thoughts / comments are welcome as always:
Thanks for looking
