Travel Logo

I haven't been writing for a while since I'm into making logo recently. The travel forum I always visit is asking for a new logo. I thought it's fun to make one, so here are the ones I made. The forum name is "四海为家".

I learned some photoshop layer techiniques while making the logos, pretty good experience and fun. Apparently, I can use layers, put things together, and may modify a little bit, but I cann't draw in photoshop, so the last one is drawn on paper. Which one is the best?
