Although I asked you myself about the graphic detail, looking at it I think that less is better. So #14 is (for me) better than #25. Perhaps it is an idea to just use the text 'Cap Blanc' as you used it in #14 and than drop the sun. And maybe play around with the word Ibiza a bit. Move it to the right or left, maybe a bit smaller. Hell I don't know... Too bad I am not a designer.
Looking forward to whatever changes you can make (if you have time)
Hi Philip, Some new versions: #40 I had already done before your last comment but I thought I might as well submit it anyway. #41 & #42 are going more minimal and have a darker grey/blue - maybe too dark?
