in firefox some of the images/text overlap. also, on your buttons the text on some is justified to the left while others have the text centered. it would look better if the text on all of them was positioned the same way. be it centered, or justified to the left. also, the text in the main text area would look more professional if it wasn't all centered and bold. the last thing is the splash page/flash animation took kind of long to load only to lead to another splash page where you need to select the language. would it be a possibility to either drop the flash animation all together or combine it with the language selection page?
i am not really a fan of the choice of colors. it seems to light overall. however, that's one of those things that are within the eye of the beholder.
looks like you are off to a good start though. good luck.
