Thank you Joy.
I did the ink sketch a year ago when I was focusing only on completing the sketch within a stipulated time, I used a reference so that I did not have to pause to make any decisions. And I was doing such sketches in the hope that it would help me overcome some severe tremors that I was experiencing in my hands. (It did help.)
I think my sketch is true to the reference picture, but I totally agree with you. As a composition, a degree of asymmetry would have helped.
