The thickness of the metal on the cocking piece/hammer looks too thin, it looks like sheet metal. The flint is knapped wrong. I'm not sure what the metal bands are for, unless they are suppose to go over the barrel, to hold the barrel on or under the ramrod to hold the ramrod on.. Usually the barrel is Pinned on. Everything is terrific, you just need to research the flintlocks more. I attached a flintlock sample pic.
