what is this

Look what I found, it's a wip of something, but what is it?

Some of you might know what it is(after all, you gave me the idea in the first place)
as for the others, look at the poses and try to guess what this is.

(yes, I know I got some of the names wrong/misspelled, I did all this from memory)


A small hint: It's based on a song. a very well known song.




I will one day finish this picture.
