I've worked out it!

What a difficult question! The pics uploaded to the blogger can not be typeset normally, and if doubleclicking the pic, the pic can not be magnified to original size!
So crazy! I calmed down, uploading the pics in an opposite sequence and deleting the redundant blanks very carefullly. Then I work out it, so great!

Thinking about.....

Can you guess where it is?

Speed roller skating

Tilting the city

I can not keep level of the pics when using my GRD II to have a snap fun,I think it's feeling about the experiences of the using lenses, I need to adapt myself to the angle of veiw of my camera's 28mm fixed lengh lens.
But I also find that the unlevel pics have another tone I pursued.
