Thanks for participating in the contest! I've been receiving alot of work from Indonesia, you guys are strong on Graphic Design! =)
So about #42 what I have to say is that I like that it is very colorful and introducing elements to beautify it makes it easier for us to market later, in this case I'm talking the butterfly. But I also need to remind you that it needs to tie in with the website's concept and have an african twist =)
OK I see that you're still going for the butterfly but butterflies don't really have that much a weight symbolically in the Angolan mind. So you might want to revisit that. Plus I found the lines to be too straight, that gives out a very disciplined look, try to soften it up and introduce some curves.
