In your opinion, what (available) faces go with certain characters?
Speaking from experience, Rawn’s Clown Clan are perfect for The Joker and Harley. That’s how I did my Avatar and Photo :D
For other characters it’s a case-to-case basis but I either tweak an existing shape or start with V4/M4 and use a photo reference to get a vibe of the character. For Fairchild, I tweaked an available face (I forget which one) to give her characteristics associated with Caitlin: elfin eyes and upturned nose. In Diana’s case I went against conventional wisdom for slightly ethnic/Mediterranean features. And for Kal-El I found two really good angles of Henry Cavell =P XD
But skin also determines a character’s appearance/resemblance. I lightened The Joker’s in Photoshop and for Fairchild, Wonder Woman and Superman I chose skins I already knew rendered well in Reality/LuxRender, all of which are photosourced.
Looking forward to hearing how others do it =)
