You might want to try a darker tulle. It looks to me like the light silvery gray has lightened up the darks considerably causing you to lose a lot of detail. That's why it's a little blurry. A darker tulle would keep your darks dark which would keep your detail. I think even over the light areas, a dark tulle would be okay, it might slightly darken the lights, but probably not enough to make a difference.
