Got to get me some of the coal black I've heard so much of. Actually can think of a million artistic uses for it.....
Regarding those leather straps, they didn't sit right with me. More so than any other part. It looks like you were either kinda sloppy with the paint, or you black lined with a color lighter than the object. Either needs cleaned up or the black lining needs to be darker. And yes, lighten the straps. Just lighten the center of it, all the way around, since that's the high point. That's what I do, for instance, with the cloth wrapped around axe handles.
