I really like #7 - it's an innovative approach to the logo. I would like to see this concept explored a little more - perhaps submitting a version with a blue cactus - as well as adding something more to the text - like changing the 'O' to a Jewish star or something along those lines.
I think that #7 is still my favorite of the logos you've submitted. I really like the cactus. I also like the natural green color of the cactus. Would you mind submitting a design that has the exact same cactus - with a sunset behind it. And then have the Jewish in white and the Tuscon in blue - all against a black background?
Is it possible to post a version of #7 with a black background? Even though the new ones are very colorful, I think that #7 is your best design yet - it's simple and really gets the message across nicely.
