The model as-is feels larger than 28mm scale. I would recommend tagging this as 28mm heroic scale or 40mm scale instead of just 28mm.

Two areas are troublesome- the strip of clothing hanging down between the legs and the grip of the sword. I would recommend adjusting the model so that the strip of clothing merges with the nearest leg. This will strengthen that weak spot with very little alteration to the mini's aesthetic.
The sword grip is just thin - nothing to change there but care is needed when removing the support.
