Adapting House Martell heraldry for miniature form

House Martell's heraldry is that of a brownish red sun pierced by a yellowish gold spear on an orange field. Adapting this simple heraldry for miniature form was fairly straightforward although some modifications were needed to spice up what is essentially a very boring design. For reference, I used a photograph of a House Martell banner on the set during the filming of a Game of Thrones episode.
