Well I want to tell you one thing is that I dont have much experience in web development field but still few things came in my mind that I want to share with you.
If possible then put some hyperlink for particular topic/place/organization/picture.
Ex.: If you mentioned that you work for xyz organization then mentioned link for that organization like www.xyz.com.
Your site contains are in center and left and right side are blank so if possible then fit it into screen size.
Mention your number of experience and organization details in career tab if possible.
