Looks to me like your doing pretty well. The design is complex but very pleasing to the eye. are you finding the slide hard to hold and hard to cut? Looking forward to your finished work - Fred
From what I can see the engraving looks very good, scrolls are nicely formed and the shading is done well. What makes it awkward is the metal finish itself, It looks to me that you have a lot of roughness in pits or machine marks that detracts from the good quality of the engraving.
