Lets start with the good points shall we? I like the way you are incorporating jewelry and the whole 'bling' factor, which is nice and suits the theme.

I also like the fact that you have been a little bit different with the use of grays/blacks however I think they are a little overpowering and dominate the whole design.

Personally I think you should start over on the navigation. The yellow is very dull and looks ‘dirty’ so use a cleaner/brighter yellow for extra impact. Also the font used is ok but the 1px stroke looks awful.

As said earlier I do like the fact you have been a little bit different by using blacks and grays but I don’t like the fact the main body is gray. Why not use a crisp, light blue or a very very light purple? And of course white.

As said earlier I am not keen on the stroke on the font used on main category bars so I think your design would look better if these were removed from both the category bars and navigation.

As far as the content goes there is not much to work with. The main aspect is the round/top scorer table so why not spice it up a bit?

I look forward to an update. Good luck with the contest.
