Scrollwork 3 (pommel)

...And now the engraving that I did on my sparring sword's pommel this afternoon. I did this with a penknife blade, not the handle, just the blade (I couldn't find the handles )
I've never tried anything of this sort before, so please tell me what you think! Any advice or criticism would be most welcome.

image and dragon design on pommel (c) me.
