I like your style and way it has been done. Can you change the square box to a more rectangular looking box? And make the rings look like there coming from the "face" of the box rather than the top?
Both of those are what I'm looking for! #11 and #10 are in the right direction! #11 is a little more complex and I like the 72 holes! Maybe try and develop it more! #10 is a simple idea of what I'm looking for so I have the simple look. Now I just want to see more complex looking designs. More detail on the ring, rings that stand out, rings that catch peoples eyes, Ect! Think that's possible? Out side of that... You have what I'm looking for!
explain how you want it modified. I focus on keeping it as simple as possible - do you want the strings rearranged? The rings different shapes?? colors??? different font style? please try to give me more specifics on what you mean by "develop"?
