Actually it does not look really good (people in here just say "Good work, keep doing it" and not actually criticize) this thing makes you to not to improve which is very ... sucky haha.
*Firstable, the green color it is not very attractive if not well used, because it is just "green", it is a common color, and most of the people are not big fan of it.
It can be well used if the web page has the theme of "Woods" you know, the theme of the forest and that stuff, it is attractive if you use it like this.
*You have placed Facebook thing first... Instead of your quick links? Really? That is not really good, that means that you give less importance to your web content.
*I do like the font from Navigation bar, they look good, but the bad thing is that the other buttons like downloads, forums, does not have a really good contrast with the background, you can use a dark-green 1 pixel stroke. It will look good and also contrast.
*I also like the triangles you have used for the "Links" "Facebook" tabs. They look good.
*The space in the middle is reallyyyy short, this is where your main content will appear.
*I really don't like the font you have used for most of your buttons, like Vote, Register, they look like whatever~~ *Also you've used bevel (bicel in spanish) for most of the buttons, which is something th at looks very common and does not give a professional look.
*I really like that you placed the registration on top, next to the header. Registration is one of the things that has to be more attractive.
*Also the Kafra next to the News content, looks like what ever other thing, and you have not well cut it. I can see white spaces next to his head.
In general bad work I give you 2/5 =/
But be happy, atleast there is someone that actually worries about your work.
You have a lot to do to improve, try to look the best designs in web so you can learn from them, also read articles in websites of how to improve, but always improve improve improve no matter what.
Look at these designs, they look really really good, one is dark, but it also looks good. Another is really colorful, but it stills look good and professional.
