I have to admit to being both intrigued and confused at this image. Of course it is a literal communication of pi is, but I find the basket and toothpicks really interesting in relation to the cold numbers. You've also used the non-scientific color of red as a background, so my mind is every which way. Hmmm. That could be a good thing!
Love that red color with the brown mat. Good job on everything else too. Nice shot of the Pi Challenge. good color, nice focus, good lighting, just a bit of shadow on the left side of your mat, but what the heck, we're not all perfect.
