This is a great start !! Personally I would say that even the 2nd attempt is too deep and I think you should go shallower, in general these lug engravings are very shallow unless looked at under extreme macro. So if you are looking at a normal photo and they look about the right depth then there is every chance they are too deep, under a macro lens they will look way to deep. I would also try to match the numbers a bit better, especially the zero, maybe they can be traced from original photos?
