Just a few observations:
1. Home -
Top right column, last sentence
Delete - visit my website(redundant)-already there.
2. Services -
Substitute strive for thrive
Change Nucules to Nucleus(spelling error)
Specify if Nuclear are deep(typical) or medium. Or available in both.
3. Products -
Delete : from tab so all tabs are uniform.
Hope that helps. Otherwise, I think it looks pretty good. Are you doing the web design yourself?
