We really like the cartoonish look of both #20 and #21. The idea is to give the customer the feeling that this is not so dangerous. How about #20 with a smaller, tighter tail flame (less or no curve, is easier to print on stuff). And both #20 and #21 with different fonts and no slogan. Also, can you try #21 with the word VACATION instead of WELCOME.
#107 - Beside making the journey to space look fun and safe, the reason I go with this design direction because I think most of the people who are going to have this 'vacation' is the same people who grew with retro scifi cartoon such as jetson etc, so it may have bit nostalgic value to them as well.
3rd place RIza!!! You were my personal favorite the entire time, but the staff had other ideas and didn't go my way. It was a numbers game, and I didn't get the numbers on my side.
