Try a different layout Ivan, something that will be more pleasing to the eye. I see your page and it makes me want to leave without taking a look at it.. sorry for being so brutally honest but you asked for my opinion, didn't you?
I would change the background color, it makes it difficult to read the text. And I would use a table, so the text won't cover the whole width of the screen.
As for the "Preview", "Enter", "Leave" images.. hmm they're not centred. Try something else.. maybe a button.. I don't know.
oh my god.. just entered the preview area.. purple text on a brown background? no no no!!
