Could anyone help me by reviewing my first attempt of routing two DDR chips?

Hello there, I have just finished my first attempt of routing two DDR chips, but I hope I can find someone could help me by reviewing it.

my project is here: GitHub - sprhawk/leaf-rv1126

it is designed by 7.99 nightly build version of KiCad.

Thanks !
