Artistic Frustration

I recently entered a challenge. I need to make 4 bookmarks with a travel theme. Easy, right? I thought it was. I had some concepts. Well, I'm not happy with my results. They're OK-but not fabulous. I want fabulous. After all, people will be receiving these and I want them happy. I'm fairly happy with one, and another one will work-I need to do it over, but I think it'll work. The other two... I'm artistically frustrated. Ugh.
