Website design - Contrast and improvement

After the feedback, I have changed these parts on the following: colour, background and  Design explanation.

Before

Now

 First, I get rid of my original background. Because it is too distracting and messy. There is too many colours on the screen and it makes users feel frustrated and annoyed. So I change it to the black background and put a big size video on it to make the theme stand out and clear.

In this part, I add the business model of my app and explain the customer and brand target.

I change all design in 2d style to make it looks more integral and use less colour to make it clear.
