My understanding was the crest of the Chief included three feathers, the three 'stars' at the bottom more or less represent the holes in the buckle, also I've been informed that the buckle image is under some protection of artwork. The image I used was aside from the stag/bush image a complete rework to include all elements of the crest while being able to be made with detail showing nicely. If any other detail was included it would not look nice, there were several iterations and several of them did not look suitable for wear.
If someone with knowledge of this can help out it would be appreciated. I'm at a loss on if this is wrong or not.
