First let's take care of #35: I saw what you did there and it was smart but remember that we don't want to be entirely tied down to the beach! =) Plus I thought that in order to make this work you couldn't use many colors and that's something we would like to see also!
Next concerning #34 I thought it a little too serious, the letters are to straight and the colors could be crazier =). I think roundness around here is better appreciated. On another note I liked when you integrated the angolan map into the design like in #8, but still I think it's a bit too serious so you might want to maybe play with the map as well
I like #40 its very suave and its easy to understand. And #45 is also nice and it's simpler. But between the two I'd go with #40 just because it's easier to relate to. Now for the positive criticism: I know you've put alot of work but I think the designs need to be a little more snazzy. They go under the radar I think. A little more impact would be good.
Ok so I think #67 is your strong card right now and its definetely the our favorite but it needs to be more friendly we think, you could experiment with that in mind and also try different color schemes. Also introducing something unique we could use as a symbol would be make it easier for us to market so you might want to ponder about that too =)
