I like what you are trying to do.
I think it needs little work though, let's think what could be improved.
The background is nice, but it's a little bit hard to read the text as it blends in with the background. Maybe you could try to give the container some background?
If it was me, I would probably give the header some background color too since it kinda splits the page into logical sections.
I'll provide an example (far from perfect, but hopefully may give you some inspiration?
