Hey Geng,I think these are pretty awesome. I like the wonky-ness in the second one. I think we will have too see how it looks with the characters in the shot before we can make a final decision but I like the direction you are going. Can you take #2 and clean it up a bit more, and maybe add the bench. I also like how in #3 you have swoopy lines pointing to the bench, can you try and see if you can incorporate some of that into #2?
Also once the characters are in the shot we can have a better understanding of the scale.
