I like #38 the best of yours. Can we play with the colors a bit? The yellow is missing something for me. And I'd maybe like to see it in white where you have the yellow with a black background.
#34 and #33 the tetrahedron doesn't work. It's not equlateral (meaning all sides are equal in length).
Thanks for your submissions and again I like #38 the best.
I also like how the tetrahedron seems to be standing up off the screen. Can you make the darker side of the tetrahedron a bit bigger and the other light sides a little smaller so it looks more equilateral?
And can you make the words 'business abilities' not so shaded?
