crucial review for redesign of my sites

[bqbq]

Hi!

I'd like you to write some tips how to improve the coming redesign of my sites:
http://www.imuridesign.com and http://www.manishtech.info

I'm interested should I change the design completely or it will be enough to change colors or some separate elements.
Also interested in some pieces of advice about informational structure of these sites.

Thanks
