Not sure about the colour -- both the drawing and the shirt.

Not sure about the colour -- the image and the shirt.

cool idea, but it's kind of bland, maybe if you used shades of green instead of tan.

I ADORE it, but I'm not thrilled about the colours either.

maybe stronger colors? nice idea though

Alright, well color can be changed. I already have several other colors saved on my computer both of design and background.

Thanks for the feedback!

i think this is too subtle in its message to get the point across. I'd like to see some really bold outlines that are more like the actual wavelengths and such that you are going for. and maybe some bigger mountains of sound on top of it to really make a grnader statement on the tee.

I like the colours, as a landscape of sound it works with muted colours of nature.

its peacefull
