i would say between 6 and seven-here's why:
the network design box is empty white. eh?
This design looks like a template. That means any 500 people might have a site that looks just like yours. Customise a color here and there.
The man in the banner looks puzzled. Maybe try a new image.
Capitalise the word "Best" in the banner text to match senetence case all other words.
The welcome message should be uppermost.
The brand buttons should fill the top frame.
