The more you do to a pic to change it from the original is better..(it shows that you put more work into it than 5 minutes)... as long as it's quality work.

I mean, the guy who posted the Lancer monster truck on wire wheels really changed up the original pic... so much so that hardly anything was Lancer related.

If you are ever interested in what real chops look like, go to DigiMods.com and look around the intermediate and advanced sections...
