Hello again,
I did a new version of the "line art" concept and cleaned up my page a bit. The direct link is:

The gnu has fewer lines than before. It does not have eyes anymore (nor would adding eyes make sense now). The main difference to me is that the first gnu looks active, while the second looks more static. I am not sure if I like this one better than the first one. What do you think?
I also added another silhouette. The direct link is: http://agnes.dida.physik.uni-essen.de/~anja/gnu/marianne-und-gnuzeichnung1.p...
The gnu's legs look fuzzy because I did not spend much effort on cutting it from its context. They are just samples, anyway. It is difficult to talk about logos without samples, so the photos came in handy. *If* we want a silhouette-type logo I would create an all original design. Only original artwork guarantees that we have all the rights to it. At the moment it looks like the silhouette idea is not very popular, so I am not putting unnecessary effort into it.
Best wishes,
Anja
