Ace is described as stocky and with dark curly hair. I slicked that hair back since Ace is pretty weaselly character and this makes him look harder than his buds. Like with all the changelings I made it so their forehead almost goes straight into the bridge of their nose. So that they are look slightly odd and close to the inhuman fairy look without going too far. Since the description for Ace is a bit sparse when it comes to his facial features I also dug up how his dad is described. So I gave him high cheek bones and a sharp nose.
