Hello Tinna,
Thanks for your entries so far!
I like your idea of the wave consisting of roofs.
Entry #39 reminds me a little bit of a tribal, indigenous design. It looks good, but isn't what we are precisely looking for, since it seems a bit too loud and playful.
Entry #38 Looks more elegant. How about a fine, sort of calligraphical curve instead of a zig-zag-pattern? The word "Suisse" is a bit to bold in both logos. What would you think of a slightly smaller font?
Your efforts are much appreciated!
