Please give us your feedback on my design?

Dear all,

Please see here our new site design:

The original layout is here:

Particularly struggling to get the fonts right, because the original design didnt use system fonts, now when we changed them to system fonts, the overall site does not look as good.

We have a tool on the site for users to increase text size and contrast, so using images for the menu its not the best option.

Any ideas? Any general feedback on it?

Many thanks!
