#17 is very cool, nice job. The frame with the #D effect looks very good. I think I would like it more without the magnifying glass and the subtitle "DATA-DOCUMENTS-SOLUTIONS" under "Discovery" like my original draft. Nice work!
#37 Nice work! I wish the blue were a bit brighter\bloder. Also it might look better if the "DS" box were closer to "discovery", this might happen by closing the gap a little between the edge of the blue "DS" box and the "y" in discovery and reducing the length of the blue box. I guess what Im trying to say is I want the logo a bit more compact. Good job, this is what i am looking for.
