#58,
#61 - These are improvements over
#50.
#50 felt a little off balanced but you're working on addressing that by putting the wave coming up on the left as well. Somehow the shading is feeling a bit flat. I'm not sure how else to put it. Maybe some of the 3D style you did on
#5 would help. I know I steered you away from the 3D, but the image has also changed since then & I think it might help.
I think I like
#61 better than
#58, by removing that inner circle.
