Very surreal. I love these weird shapes and whateverthings you have included. That thing there looks like water.... ..or sound as the title says :P I find those photoshopped lines on the left a bit interrupting. they steal the attention from you "sound". Those blocks on the right balance the image but the effect is maybe just a little too strong. Colours are great. That's the thing I like the most in this piece (but let's not forget those great shapes and detail). Altogether it's a very strong piece and I ike it a lot :)
I was busily trying to figure out what it was before, but i guess that doesn't matter since it is really cool. it does remind me of water, which I suppose is like sound with waves too. very pretty colors.
