I find small inlays to be easier than the big stuff. They are usually shallower, and take less time than a lock, for instance. Barrel tangs seem to be problematic, since it is so easy to get false printing with the inletting black. When I switched to soot, it made it a bit easier, but still not simple. Take your time, and learn to read the printing, and you will do well, I am sure.
