Thanks for your entries. Could you add some detail to the continent of Africa? It's very simplified and I'm not sure people will get that it represents Africa. Also. Stay away from Red. Not a color I want to use in my logo. Try making the image bigger, adding detail and changing the colors around some. Remember, I am appealing to Adult men and women who'll be spending $5000 + dollars to travel so it needs to be professional and adventurous.
I love the text font for #44. It is a little too busy now but on the right track. Could you try a key hole instead of a circle in the center. Great effort.
I really like the background images in Africa for #46. I don't think the key hole works though. How about a magnifying glass? In the lens of the magnifying glass, put a village setting with a hut and some people. Try a few different things that you think might work.
