Hi Justin,
You are doing well. Here are some suggestions. Learn to vary the width and depth of your lines to suggest relief. The outline of the flower, for example should be wider and deeper cut where the petals appear to lift up (the concave parts of the edge). Control and discipline your shading lines. Try to keep them either parallel or evenly converging into the dark area of the design. The initial line for the nick and dot border should be heavier. Then, if you are going to apply Schipper's method, grind a square graver to about 110-120 degrees so it makes a wider notch or nick. Your evenness is very good but I like to see a more rounded appearance, which can be achieved with a heavier initial line, and wider and deeper cut nick. As I was learning engraving, I found cutting parallel lines was the single most effective practice for learning control. After cutting straight parallel lines, then try to cut a series of evenly nested ovals or circles. After succeeding at those exercises, cutting scrolls and flowers will be easy. You've made a good start.
