I'm pretty much of the same opinion as MightyPete with a good sprinkling of what jstro said. I personally wouldn't enter a 'reproduce this' challenge, but that's because I spend all my time at work doing pretty much exactly that with no room for personal creativity. I don't want to do it in my free time as well! I much prefer the more open theme based challenges. That way it's as much about your imagination and skills in translating that into artwork as it is about your mastery of Vue. In other words it levels the playing field - you might not be as good as some others here with what you can get out of Vue, but your image will shine (and win!) because it shows amazing creativity. If it's just a 'copy this' challenge, then the emphasis is entirely on how good you are with Vue... imagination not required. I also don't mind postwork at all - in fact I think it is a good thing; there are just some things that you want to convey in your image that Vue can't do. But yes, you should declare what postwork was done. My tuppence worth.
