Hi my name is Kit. First time posting here. Chrishirst - agree with his comments. Would only give it a 6 out of 10 though for design. and a 2 out of 10 for marketing. At least both of our numbers add up to 8...right?
Not a fan of big headers full of whitespace - it doesn't really provide any value to the user and it's not beautiful.
It seems as if your English is off in a lot of places.
You do 3-d visualizations, but the rest of your landing page is about Marketing...in Boston?
Also the clients you have logos of, the quotes aren't from them - there's not connection and it's a design disconnect
The map provides no additional value, not even as a contact.
I would recommend going back to basic marketing - who is your target market, what do they want, where is you traffic coming from, what is their buying state, etc, and address those things with a cohesive message and design.
