Interesting cube...I like the color gradients. Did you mean to include the "Escher Effect" on the bottom interior crossbar? If so, then I wish you had emphasized it more with shadows, etc. I love the colors and the "unfinishedness" of the cube...but I wish you had selected a different sky and maybe a different ground. To me, the "primary colors" mood of the cube doesn't fit with the "dreamscape" colors of the sky. I hope you do more of this sort of thing, since I think you're on to something good here!
Thank you, I chose the sky as it did not dull the colours of the cube but you are right a different one could have made it look better. Yes the effect was intentional and I think you are right shadows would have made it a little better. I will be trying more of these in the future. :-)
