The boxness is too much for me, add more white space, and remove the combination of simplicity at the top, with tables at the bottom. Sponsors should be more of like a reel, make them in one line, but a list that scrolls up.
Second impression is to not attract attention to breaking news with red highlight. Nono!
Contact Us should be in footer.
Fix header, left align title, change font, separate nav, maybe even into sidebar.
Get a more web-friendly background image, this will load for AGES.
Otherwise, good start, but keep working at it!
Aside from the previous two comments, the bottom "sponsors" are not aligned to anything (make them left aligned with main content box).
Those white boxes make my eyes hurt - tone down to a warmer colour (light green, or transparency).
Bg pic is just cut off at bottom - can you make a soft gradient to green?
make a cool typographic title! you can do something neat for the site header, i am sure of it. make it in a design program, and bring it in as an image, instead of just typing plain text and making it big... that green is very middle gray.. its hard to make black or white really contrast on a color like that for reading... i would just choose another background.. and yes, definitely tone down those whites! keep going with it, oh and you dont need those icons for the navigation bar (home, ..?? and scheduled events) the simple word there alone without an icon is more sophisticated. you'll get there, keep working on it
