for one thing - without telling people what rolling stock is, most people won't know. also many think that entering contests will help them sell better and they are right. but they tend to not follow the rules, but that won't help them. i'm surprised its as low as 25% though.
many people haven't a clue how to edit their images. they think a gallery is a place that anything will sell. but they don't know the basics. at some point they will come in here and say - why am i not selling? and then we will tell then.
i just use these to advertise in, i don't much care what was entered.
the most important thing about these contests
1. they have no prize, and there isn't much glory, so who cares..
2. many have no description, or it's really confusing.
3. many don't have a proper example as a photo, for what they want.
