Hi Mike,
I think you've done a nice job on the restoration. Because the image has yellowed badly, it has lost some punch. To my eyes, it could use a little more contrast. I think I would lighten the whole thing just a tad, and lighten the dress quite a bit. I think that would make it look a little better, but that's just an opinion coming from one without a whole lot of ability.

Keep up the good work.
Ed
