Please view the below link to get an idea of what you have to re-create:
Each of the 5 numbers on the mock up need to be re-done. The below numbers pertain the the numbers in the above link:
1.) For #1 feel free to use a real stadium with fans (be creative)
2.) For "Nav Bar A", the text must remain in the exact same area. You are changing the background image and possibly the color of the text if you feel it is necessary.
3.) For "Nav Bar B" to use the same text that exists as of now. For these, you are simply re-doing the background and also making the text clear (feel free to change colors and background images. Expand this nav bar so it uses the full width of the screen and in doing so please increase the font size by 2 sizes.
4.) For this section, you are re-doing the background stadium Seats so they look more clear. Feel free to have fans be sitting in these seats. You can even swith up this image if you can come up with a better idea, but this is reccomended.
5.) The border of the app symbolizes the grass and lines on a baseball field; if you can come up with somehting different feel free to submit, but this is recomended. Feel free to make the grass look better so it does not look so pixcellated.
