I like the more organic feel of this piece--so many creations like this have only smooth edges and clean lines. I also like the little strands of color that wind around the larger elements. One little critique I'd offer is that the top section seems a bit more bold and solid--and it doesn't have really any of the smaller elements included below. This isn't bad, and I like the texture in this area, but it feels slightly disjointed from the lower portion of the picture to me. But overall, great work. Very interesting.
Thanks for your comment When I made it, I though at contrast of the shapes like contrast of the colors ! The top section is bold and the low section is organic, it's a real explosion like in musical composition. There is slow and low, there is quick and loud... It's a little bit mad !
