Smith apron details

Added some detail to the apron, with some knotwork on the straps, a scaled texture, and altered the pocket and added a norse style dragon there. Went through a number of different styles for the designs and the scales before settling on these. My idea behind it is an apron made from salamander hide, which is ancient and has been passed down between Dragonsmiths for a very long time. It's salamander hide rather than dragon because it wouldn't fit for the character, who is allied with the dragons, to be wearing one of their hides. It couldn't be regular leather either though, because that wouldn't protect the Smith's unscaled belly from the heat of the dragonfire. Still need to go in and add texturing and signs of wear and tear.
