- Remove your logo from the header. Your users already pressed the icon on their homescreen to launch your app - they're not confused about what app they're looking at.
- Settle for fewer textures. You have two distinct wood textures that clash, and paper scrolls on top of that. You can distinguish yourself without resorting to a custom background for everything. All the texture obscures the things users can interact with (the refresh button, the scrolls, etc).
- Make the text bigger/make the contrast stronger. Take a look at any app you read a lot in - the font is generally significantly bigger, and on a more distinct background. You're trying to make it look "old" - try old parchment. That's a much more reasonable than a wood floor for reading text.
