Not sure what to make of this
It looks to me like a slideshow of two fan art pictures. If I were to make a slideshow, I'd have at least half a dozen pieces, no matter how good they are - the art is great in the second pic, while the first one looks like an original piece which has been altrered slightly, by adding the two characters flanking Bitey's silouette.
Don't get me down as a critic of this, but I think that you may need to make more of an effort to get this passed on NG, but you can certainly go back and work on getting more pieces into the submission, since the filesize is onlt 650k, you've got plenty of space to add things.
The navbar at the top of the screen is great, except it moves around between pictures, I'd reccomend leaving it in the same place, so you don't confuse people.
