You have a very nice looking forum. I like the skin and the buttons go very well with the the skin. The forum is quite active from what i can see and your members do seem to keep returning as 1118 posts between 41 members is very very good. It has a very nice relaxed atmosphere and there is a wide range of topics to discuss. The logo i think is very good as on most forums i don't really notice the logo although on yours every page it stands out which i think is the sign of a good logo.
As for improvements that can de done i can't really see anything that needs to be improved or changed much.
