#37 - I like it especially the font and the lightning inside a letter graphic. I have some ideas for your consideration. What do you think if the "international" is bigger? And I can see that in the graphic you have a lightning inside the letter "G". Would you consider to change that to a lightning inside a letter "P" instead? I believe it will look really good.
Also, I like slightly gradient. So, for the orange, it might be be better to adjust the gradient so that the different between the light orange and the dark orange is not much. You can keep the dark orange; just change the top, light orange.
