No.

Unfortunately, we do not allow for updating or replacing of artworks already submitted as any ratings, comments and links would then become irrelevant since there would be a new artwork on an already existing page . You will be required to create a new page for any new artwork. Even if you wanted to replace an artwork for quality or new format purposes, you will have to upload this replacement to its own new page.

You can always edit the original artworks description and direct a user to the new replacement.
