Hi Scott,
Your concept in my opinion depicts a very strong, reputable and professional brand. I would have confidence in a brand that looks like that over something thats more artistic / busy like the other concepts. I see lots of potential from a luxury branding point of view with that logo vs. the other entries that have been received. Only thing just need to make sure that the logo doesn't match up another brand (that would hurt Jetari in the long run). I'm assuming this is a unique concept to you?
I think the typography can be changed around and the placement of the text can be moved around a bit (try moving to the right of the icon).
The only downside to this concept is that Jetari is going to be targetting more of a female audience. With that being said more than appealing to a female audience, the logo and branding needs to represent quality and confidence which I think that logo does quite beautifully.
Scott could you play around with the typography without killing your concept? A font face thats not "gurly" or busy with curves but something a little bit more appealing to a female gender?
Thanks,
Charles Edmunds
