Well, since you asked, I'd say the gun is pretty well perfect as it is. It's minimally engraved, but tastefully so, and the stock is appropriate to the gun. It looks great as is, in other words.
I would not go for case coloring, as things can happen during the process (I understand) and a few thousands can make a difference in the way a gun works.Plus a gun fades gracefully. That's part of its charm.
The stock is excellent as is. The instinct is to remove the plain stock and put something stunning in its place, but I think that would be a mistake and to my eye, the gun would be "overstocked." Overstocking a gun can draw too much attention to one part of the gun and thus take away from the rest. Right now, the gun is asthetically in balance. Fancy wood requires, IMO, more engraving than your gun has.
Plus all those things cost a LOT of money, and you'll end up with a gun that's not worth any more than the price you paid for it.
