/diy/ - Do It Yourself

Hello /diy/,

Here's the results of a high schooler's first time trying out PCB design. It's the control board for a quadrotor that has an XMEGA microcontroller, accelerometer, gyroscope, and CC1101 radio. I'm still new to this kind of stuff, so I would appreciate any sort of feedback on my design. Any electric engineers?

Things I'm worried about:
-The rather random routing of the power supply lines
-Running power and other lines below ICs
-Running traces between pin holes for the servo and ESCs
-Placement of crystals and antennas causing interference

Thanks in advance,
