Some very impressive murals! My favorite one... quite weirdly, it's the one you took in the rain. Not even the mermaid you mentioned, though she looks pretty cool herself, but the whale-shark where your camera got a few raindrops.
I used to make these compilation style posts too, but then I felt that focusing on one mural only in each post gives each mural the attention it deserves. Later I started participating in CCC's Street Art Contest, which is a beautiful place to share murals. I can highly recommend it, and I'm sure the murals you found would get a lot of good attention there.
