I liked the first one. It looks like some "hero" (based on what he seems to be wearing), leaving for some situation that he will be in a great danger, and they seem to be on that potential last kiss.
Although he looks like a racer or a biker, anyway, we can still work out some dangerous situation that could make an unstable love story.
I donīt know, if you like my idea, let me know. If you think that I went crazy, also let me know.
