Todd, The effort tapers off over time when your first starting leather carving. Your first try is way better than my first.
Try adding a few decorating cuts with your swivel knife on practice pieces. Make sure your knife is very sharp and then settle on some cuts you think dress up your flowers and stems. It doesn't take much.
The more you use the swivel knife the better your cuts will be (also a good use for scraps)
You will see a flow in your stemwork as your skill with the swivel knife gets better.
I've never finished a piece that I thought was a match to what mother nature looks like, kinda hard to match ma nature with a piece of dead cow.
