Prepare a layout diagram with ATMega32,BMP180,OLED and SD card

I'm preparing layout diagram with below requirements:

1) ATMega32
2) pressure sensor BMP180 (Bosch:http://www.kynix.com/Parts/2531993/BMP180.html)
3) OLED display
4) SD card

I would like to use power bank as a power source (I'm using Microchip TC1185 to get the right parameters 5V->3,3V)

Reading ducumentation about BMP180/sd card/oled I have created diagram, but as a beginner I'm not sure if there is no mistakes.

Please share your thoughts about this diagram.
