I quite liked the image when it was put up as a print last night and it had more of an impact than it did on the screen. You are right that it printed darker, which can happen if you do not have full colour management in place. If your monitor's brightness is set too high, for example, then it will not give a realistic impression of how images will look when printed. Also bear in mind that photos are taken with and displayed on screen with RGB devices, i.e. the colours are from from combinations of red, green and blue. On screen, they are illuminated by backlit lighting. Prints are made using the CMYK process, i.e. combinations of cyan, magenta, yellow and black (K) and are viewed by reflected light. Not only that, contrast is lower than on screen. Getting the two to match is not always straightforward!
Regarding the vignette, which also was darker than the digital version shown here, it can be an acquired taste and often less is more. If it is noticeable, then you have probably overdone it and applying it more subtly can often produce a better overall result. At a subconcious level, the eye and brain will still pick it up but not to the extent that it becomes obtrusive.
If you do your own printing and an image does not come out as you wish, you have the option to make adjustments and do it again. It is worthwhile to give the print a few minutes to dry completely before making any alterations as colours can change during that period.
One of the reasons why I could never be a judge is that assessing an image is very subjective and opinions will always vary between individuals. What I look for is someone who can give a critique which justifies the eventual mark by highlighting what they see and any improvements they feel are necessary. If you have ever seen a competition where there is more than one judge, it is actually very rare that each will give an image the same score and the variation can sometimes be quite large.
