I would like to see a design without the slogan. It is too big in your designs. Also try to find a more simple design for the font. I would like to see you add an icon to the design. It would be best if we could use it both as a stand-alone icon but also as an icon beside the text - for example on our website.
#64 and #65 looks far more stylish than #43 and #44. I like the simple text. Entry #65 is your best so far. I really like the way you have cut off the radial gradient at the bottom. That really highlights the text. I would like to see some changes to the wordmark (icon) though. Can you make an example with blue colors? Maybe also one on white background (with blue colors) and without the glow. This is because I would like to see how it will look on other applications other than our website.
I like the blue colors of the new design. But you have to do something about the black "t" in the icon. Its a little hard to read. I think you have to be a little more creative to make the "TB" work for the icon. Maybe you should try to make something abstract?
