The header needs to be more appealing. the directory boss wording (Imaging) straight up looks amature. The coloring can use a little work (maybe less generic coloring)(any real bright colors or strong colors really takes a toll on the eyes). just a few things so far but that should keep you busy.
Page rank image not showing http://www.seozone.in/pagerank.php?type=display. The logo is too weak and being overpowered by the graphic to it's right. Don't like the use of Alexa ranking as it gives a flase impression, if you have it high people won't believe you if you have it low people think your not worth visiting, waste of time imo. Good luck.
You may wanna know, I was the original owner of this website. As aspidov said, you may wanna get a new theme, upgrade the latest script version. There is lots more to add to it as the ex owner didn't look into the site from months.
