Your carving itself appears very well done. I think there two design factors detracting from the overall appearance of the carving. First, like Rich suggests, I think the overall lock area in general has too much wood remaining giving it a “boxy” look.
Secondly your carving design seems to just “parallel “ the outline of the lock panels lacking a little flair in a couple of spots, and may have a little too much flair when it comes to the elongated teardrop shaped beaver tails.
I’ve made a few marks on the accompanying photo to show the areas that I think could’ve been shaped differently, but my limited editing skills only allow for a crude representation rather than a true redesign.
Keep at it, you’re doing much better than many.
