What can I do to make my layout design, more similar to Clean Master app's layout?

What can I do to make my android (xml) design, more similar to this app screenshot?

Basically I've seen this application screen I liked the look of, and I've attempted to make my design match it as closely as possible. But although my design does look similar, it doesn't look anywhere near as good.

What other changes do you think I should make, to make my design look as good as the screenshot below. My code and a screenshot of my design so far are also below

To be more specific, the parts of the design within the screenshot I'm having difficulty duplicating are:

• keeping the rounded edges to just the top two corners of the blue section
• my percentage bar, looks no where near as good as the original
• The four square white buttons, from the white section of mine look no where near as good. And I can't quite figure out how to fix mine to accomplish the same.
• The font color and style of the original looks fantastic and well mine doesn't

I have made an attempt in each of the above, as you can see below. But Any help would be, much appreciated. Thank You
