Hello! Here is my idea....the many circles represent vocal waves in a way - your groups - different volumes, different colors, different textures - all combining to create harmony and balance. I've uploaded a couple of variations on layout and colors - let me know if you like any of them and any changes you would like to see!
Cool idea! I tend to like the variations with fewer colors. Definitely a very contemporary design. My only thought is that the design with the circles might be hard to figure out what it was if it was on a t-shirt. I really like the colors you chose - especially the aqua variations. I also like the black and white version. How would that one work on a black background? Dumb question I guess. :) THanks for your entries.
Thank you for the feedback! Here is a black and white swapped version! and one where its smaller on the screen so you can see what it will look like embroidered.
