I have had this image forever and I have always loved it. They look like they are going to one of the rave parties me and my sister go to XD. This render is amazing wish i know who did it O_O' .I didn't do much to this one I just did some super croping XD and played with the contrast and shadowing and added the text
Maybe that was alot XD
