Just like many of the rest of us, you went without a patch box for your first build, and no carving. You got it done as quickly as you could, but still payed attention to the quality of your work.
I guarantee that on your next build, you will want to add more features, such as a patch box, raised or incised carving, inlaid pieces, wire, and maybe even engraving. And, you will take off more wood, will take you much longer to build, and you will be less satisfied with it when it's done.
Your third build will be less ambitious than your second, but your execution will be better, and take you less time to build.
Your fourth will be better than the third, and slightly more ambitions.
Your fifth will take you at least 4 years to build and be a masterpiece, incorporating all the things you learned making the first four, and you'll spend about 800 hours on it.
And on and on it goes, until your estate will sell off your partially built last rifle.
