How do I change my icon in the Hall of Fame?

When I completed the first campaign of Heroes of Might and Magic V I was taken to the Hall of Fame and was shown my place on there, in my case it was third.

However I seem to have an icon of a Vampire Lord, the same as second place Ihora and I'm not particularly fond of it. I looked in the Settings menu and the Profile selection and I can't seem to find an option to change this.

So how do I change my icon in the Hall of Fame?

NOTE: i'm playing version 1.6 using the H5_Game.exe in the bin folder (not the one in the bina folder which i assume is for the first expansion)

Not sure how it works in HoMM V, but in previous versions of HoMM, the icon was directly related to your score. To get a different icon, you had to get a higher (or lower) score.
