Arduino and Gyroscope

I got this task in my internship, where I have to design SMD based ardunio and gyroscope sensor control, which turn on or off the light in the depending angle of wrist. I have to design this in a wearable design. in given dimesnion.

ATmega328 - 28 pin - VQFN IC
12 SMD LED's connected to 12 GPIO's respectively 
MPU6050 -  6-axis Accelerometer & gyro sensor - connected to 2 GPIO's as I2C interface
6pin -  2mm pitch - ICSP programmer lines for Atmega328 microcontroller 
3.3v regulator - SOT25-5 pin regulator
3.7v Li-Po battery connector - 2 Pin JST XH Male Connector – 2.54mm Pitch
Design a 2 layer PCB with the below mentioned details:PCB dimensions: 42 x 40mm
