To support the community that's why. I think this illustrates the real issue here. It's really a phillisophical one when you break it down. I'm in for the fun and have no expectation of winning anything. I'm not that good and I know it. I just enjoy participating in the community and the contest is a huge event within the community. In my opinion, if all you ever do in life is participate in things that benefit yourself your in for a lonely ending.
Look, this isn't a sport or a game, it's an art contest. It involves modelling and photography with a little bit of writing. It's totally subjective. Everyone here knows you can hide a lot of mistakes with the right camera angle and lighting. I've had the opportunity to handle models in person that looked perfect in photo's but were way less than spectacular when seen in person. Surprisingly so, i might add.
I've been giving this a lot of thought and there are two things that I think would be beneficial. One would be the mandatory blog and the second would be to allow more photos. Say 3-5 mandatory shots and 10 -15 of your choice. It was hard to make some decisions last year during the voting and more detail photo's would have really helped. Some may say the blog is giving away secrets but I've never ran across a modeller who wouldn't share his or her techniques. I think it would make the comp even more fun.
Also, I can see splitting out the youth to there own division but other than that I really see no reason to divide things further. Even then I've seen some youth builds that are quite a bit better than most of mine and I've built hundreds of kits over the years.
There's really no right answer here. We all have different personalities, ideas, and motivations. these kinds of discussions have been going on forever. One thing is for sure. No matter how or if the rules change I will participate to participate. Not because I have any chance at all of winning anything but because I enjoy this community and the members of this community. What's a few bucks to "hang out" with some of the best people and modellers on the planet?
