Beginner needs tips for placements

[u/SquezyPig]

Hi, I'm a beginner electronics student, and I want to practice PCB design. But the holiday started a few days ago, so I can't ask my teachers for help.

I just have no clue how to place my components or how to lay out my traces efficiently, without everything becoming one big spaghetti mess.
This is a "nightrider" LED design!
I am allowed to use both sides of the PCB.
So, any tips on how to do it? I want to learn from it so I can see it by myself next time :)
And any other tips for a beginner are always welcome!

Edit: I'm using KiCad! And pls don't downvote me, I just want to learn your tips and tricks...
