The homepage looks a little php-nuke ish which I've never been a big fan of, but the forum itself looks good, nice color and a clean theme. Maybe look for a subforum mod such as
https://vborg.vbsupport.ru/showthread.php?t=177954 so the list doesn't go forever. On the home page maybe try aligning the type left instead of centering it in the middle area. Also because of the bigger left column and the images in the center (like the itunes card) it makes the type feel off center to me. Also, redo the poll images (bars), the stock ones are too chunky and colorful for your theme.
