Perhaps #50 and #51 are a direction to explore. How would it look if there were more than two people? Perhaps several circling the sphere? It is very pretty..... I also think the legs are too spread out.
I also like #49, but I would love to see a different font used for the name and a little less of the sharp edges in the cut of the design. Do you know what I mean?
Thank you for your last minute entries! I will rank them, but they are hard to really see clearly. The colors make it hard to see on a white background, and "Institute" is a bit too small to read. Still, beautiful images!!
