I have just ranked your new entries. I like the style of #53 more than #54. That said I think it is a good idea with the visible "T" in #55. But the style is not quite what we are looking for. The "exploded" style of the icon in #53 is better. It looks more stylish and modern.
Try to tweak the colors. I like the blue of "NDY" from the gradient text. I would like to see you replace the orange with another color. Maybe blue and black/gray, blue/blue (darker blue) or even some white instead of the orange. If we chose to go with orange I think black and orange would be better than blue/orange.
Our new website has blue elements in it with a light gray background. Content pages are white.
