The layout and design of the site is good but the header does not look so good, the graphics in the header does not look good. You should get a professional logo and get some better graphics for the header.
I quite like the site and think you have done a very good overall job. However I think you could improve by adding a nicer header, maybe with some relevant pictures and definitely agree you need a professionally done stylish logo. This would make a big difference and really complete the website in my opinion. Great job though
