Hi Neil,
That’s a good question! The reason I hooked it to the right was simple due, in my opinion, to leaving the design “open”.  I am in the process of drawing two more similiar designs but this time try and make them a little more flowing and less busyness in the center.  I’ll show you what I mean when I complete the drawings.  Hope I made some sort of sense in answering your question.  Go ahead and give it a try if you wish 🙂  since I’ve been a wildlife artist since 1974 I want to try and incorporate chip carving with flora and fauna, as well as trying to developed my skills with all the geometric designs available.  Thank you so much for responding to my work! :-).   Mark
