Sorry to come to this late but I have a suggestion.
Reference the discussions about tools:- You could try something like the Internet Ray Tracing Competition (http://www.irtc.org) in which the competition entries have to also send a text file containing some mandatory fields. This text file will be viewable along with the image by judges and the general public. This would allow judges and the public to consider how much a given tool helped the entry and - if they so choose - reflect that in their rating. Of course there would be no requirement to consider this and the file could simply be used for information/reference purposes.
Cribbing heavily from the IRTC site the file might contain something like this..
Mandatory Fields:
USERNAME: <Your Muvipix user name>
DECLARATION: I SUBMIT TO THE COMPETITION RULES
CATEGORY: <The category of the competition you are entering>
TITLE: <The Title of your creation>
SOFTWARE USED: <This would include PE, After effects, PSE, MSPaint etc.>
Optional fields
DESCRIPTION:
<anything you want to say about your creation's content - location, actors, background, inspiration etc.>
HARDWARE USED: <PC Specs for rendering, video/still camera used , home made steadycam etc. - People are often interested in this>
DESCRIPTION OF HOW THIS ENTRY WAS CREATED:
<Description of how you created your entry, what techniques you used, what caused problems etc..>
Just a thought.
