Contrast and visiblity - since everything is grayed out, it might be difficult for a user to know what is what, try changing bg image to a colored one or something else to differentiate between bg and content.
Instead of content being left aligned try centralizing it
Use uniform layout for eg about is different from services
Emphasize on homepage that this a coming soon website page. No user will understand the meaning of that countdown or why that subscribe button is there. Also try bringing the subscribe button above the fold with clear description of what it means.
Some visual hierarchy and fine tuning of typo can be done.
All the best.
